Cel-Fi PRO Smart Signal Booster
NEXTIVITY’S 3RD GENERATION Cel-Fi SYSTEM adds substantial capability over our previous versions. The Cel-Fi PRO is designed to dramatically improve voice and data coverage in up to four bands for 3G, 4G and LTE for consumers while significantly improving network capacity. Good things do come in small packages: Now with LTE support, Cel-Fi is compatible with the highest data services application available. All new patented echo cancellation algorithms enable Cel-Fi to offer even higher signal levels throughout the coverage area than before.
Benefits:
- Has Improved Voice Coverage. Enables clear and reliable voice connections within the coverage area —13,000 Sq. Ft.
- Has Improved Data Throughput. For indoor areas with poor reception, Cel-Fi offers significant data throughput improvements for HSPA+ or LTE — often achieving a 4x improvement.
- Has Improved Battery Life. Cel-Fi manages the power levels between the cell tower and user devices so that subscriber devices enjoy significant improvements in battery life.
- Extremely easy to install. Cel-Fi is a true “Plug and Play” system that doesn’t require the installation of external antennas, bulky coaxial cables or a configuration set-up by the subscriber. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment — including changes made by the Operator or those caused by nearby user equipment like WiFi, or other Cel-Fi devices.
- Reduced Churn. Fewer dropped calls and higher data rates help ensure customer retention.
- Higher Data Service Usage. By supporting advanced multi-carrier features, the third generation Cel-Fi system ensures that customers can maximize their data rates.
- Decreased Operational Cost. Lowers cost of indoor coverage and increases capacity of WCDMA and LTE networks.
- Network Safe. Cel-Fi’s embedded System-On-a-Chip technology provides real-time and automatic end-to-end gain control, thus guaranteeing it will complement the existing macro network’s capabilities.
- Operator Specific. Cel-Fi’s On-Board IntelliBoost processor securely manages the enhanced services only for the Operator who authorized the system.
- Self Adjusting. Cel-Fi automatically selects the correct frequencies for use based on channel frequency and Operator PLMNID codes, thereby eliminating additional and costly Operator provisioning efforts.
- Multi Technology Support. The Cel-Fi PRO can support both WCDMA and LTE across four different cellular bands in the same system.
- Multi Carrier Support. The Cel-Fi PRO system simultaneously supports multiple carriers with bandwidths anywhere from 5 to 20 MHz with a total system bandwidth of 35 MHz.
Cel-Fi Features:
- Fully wireless, plug-and-play quad-band architecture for supporting—WCDMA/HSPA+/ LTE, with up to 100dB of system gain in each band simultaneously.
- Patented 2-unit, 3-hop system allows flexible placement for optimal coverage.
- Processor running advanced digital echo cancellation and channel select filtering algorithm.
- Software-based optimization of integrated antenna coverage pattern which maximizes system gain and provides improved coverage and signal quality.
- Automatic Gain Control (AGC) continuously monitors system path loss and transmit power to deliver maximum gain.
- Intuitive LCD User Interface (UI) allows quick and easy installation by end-user.
- Cel-Fi PRO External Antenna Connector SMA-Female (EXA) variants feature an external antenna connector to enable the use of an external Donor antenna. A Cel-Fi PRO EXA with an external Donor antenna can thereby acquire an outside signal, allowing it to be used in applications where no signal is present indoors (i.e. cement, metal walls, etc.). This opens up new opportunities for using Cel-Fi PRO Smart Boosters when other solutions fail.
- Cel-Fi PRO EXA enables cellular coverage in hard to reach places by allowing the Cel-Fi Network Unit to be placed, where no service exists.
High-Level Specifications:
- Support for 3GPP HSPA Rel. 10 features and 3GPP LTE Release 10 Features
- 5GHz link compliant with FCC Part 15 and EN 301 893
- Up to 100dB path loss between units (approximately 20 meters between NU and CU) • Max EIRP for Multiple carriers: 16dBm downlink & 24dBm uplink
- Auto-Configuring “All band scanning” feature to self adjust as Network channels change
- Multiple band configurations available. Check with our Sales rep for details.

Better off saving your money for a quality brand like Acer or Samsung
Size: 24"/FHD/240Hz
If you were looking for a decent gaming monitor with a good refresh rate, you better keep looking. Honestly, I wanted to really like this thing. For $120, it ticked off a lot of great features for me: at least 120Hz refresh rate, 1080p quality, and some nifty reticule marks for FPS gamers like myself. And for a year I had no problems with it until a few days ago. The ability to control input's, power, and toggle the reticule features all lie on one singular button behind the monitor. Here lie's the issue; if that power button starts messing up, there is no way to control or turn on/off the monitor. This is exactly what happened on my unit; the power button/control went out and the monitor was basically useless. I contacted Koorui support via email, and all I got was a vague "Did you confirm the button is really broken" response. Replied back that I did, and the manufacturer has ghosted me. Basically, I HIGHLY advise you just save up a few $80 or $100 dollars and get a decent entry level gaming monitor. By going cheap with this one, you will just end up probably wearing out the power/control button and be left with an expensive paperweight. If you are DIY repair savvy, I am sure that replacing the power/control button probably is not that big of a deal. In which case, go right ahead as it is a decent monitor for the price. But with that said, having this thing break leaves you with basically no options to get it fixed and good luck trying to get a hold of Koorui for support. Sadly, this is a growing trend on buying electronic's here on amazon from smaller brand sellers.
*Update* So as of writing this review, I got Koorui to reach out to me. They would agree to replace the monitor for free, but I would have to front the shipping costs. They have their operations out in California, so if you live on the east coast then expect to pay around $40-50 for shipping for the monitor all the way out there (nearly half the monitor's value). I told Koorui that this just did not make any financial sense and they offered to refund me 50% of the monitor's value. However, they have yet to specify how they will send the refund, so I am unsure of whether I will see my partial refund when this is all said and done. So know that if you do proceed to get this monitor and need to return it past the 30 day return window covered by Amazon. TLDR: just save up an extra $50-100 for a big brand gaming monitor and save yourself the headache of dealing with all of this.

I feel fully enveloped in the work
Size: 34"/WQHD/1000R/HDR400
Changed my work at home experience. I feel fully enveloped in the work. I don't use it for gaming so can't comment on that. But for laptop heavy work days, this is a great experience.

Koorui 34E6UC (34" 3440×1440, 180 Hz, 1000R curved VA panel) — But Missing Info Buyers Should Know
Review:
I purchased two of the Koorui 34‑inch curved ultrawide monitors for a dual‑monitor setup, and so far I’m very pleased with them. The picture quality is sharp, the brightness is solid, and the “Normal” color preset looks natural without any adjustments. For the price, these 34‑inch panels deliver very good performance.
That said, there are a few important details the product listing and reviews don’t mention — and knowing them ahead of time would have saved me some stress during installation.
1. YES, the 34‑inch model DOES include stand‑offs (spacers)
This is not mentioned anywhere in the listing, and even Amazon’s Rufus incorrectly says they are *not* included. They actually come in the small accessory packet with the manual.
If you’re mounting these monitors, you will need those stand‑offs because of the recessed VESA pattern. They are already in the box — just not advertised. I rushed to order a separate spacer kit because the listing didn’t mention it, so I’m putting this here to help the next person avoid that.
2. One of my monitors flashed briefly until I disabled FreeSync
On one of the two monitors, I noticed a quick bright “flash” when moving the mouse. Turning off Adaptive Sync / FreeSync in the monitor’s menu fixed it instantly. The other monitor didn’t have this issue, so it seems to vary by panel.
Not a defect — just something to be aware of if you see flicker or brightness pops.
3. Color and brightness match well once set manually
After setting both monitors to the same brightness, contrast, and color mode, they match very well side‑by‑side. The “Normal” color preset looks the most accurate on these VA panels.
4. Build quality and packaging are solid
Both monitors arrived well‑protected, and the included cables work fine. The stand is basic, but I’m using monitor arms, so that wasn’t a factor for me.
5. Too early to comment on long‑term support or durability
I’ve only had these monitors set up for a few hours, so I can’t speak yet to long‑term reliability or how responsive Koorui’s support is. I’ll update this review if anything changes over time.
Bottom line:
These 34‑inch Koorui ultrawides are excellent for the price, especially for gaming or a dual‑monitor setup. Just be aware that:
- Stand‑offs ARE included (despite the listing not saying so)
- FreeSync may need to be turned off on some units
- Picture quality is great once you match settings manually
- Long‑term support is still unknown
If the listing had mentioned the included spacers, it would have saved me a last‑minute order — so I hope this review helps the next person.

Awesome monitor! (my 3 year review)
So I've owned this monitor for about 3 years now and here's what I have to say about this monitor. The picture quality is actually really good. I got the 1080p version and I mostly use it with my Xbox series x and occasionally will use it for some lighter gaming on my gaming PC both work effortlessly well. The screen size is okay I think next time if it's in the budget I'll buy there 34 inch curved monitor. But for right now I'm sticking with this monitor until it dies and so far it's running strong 3 years later. Right now this monitor cost $80 which is an absolute steal at that price. I paid $130 for it and would say it's absolutely worth getting. There's no flickering. The setup process went smoothly. It's compatible with both my console and gaming PC! I absolutely love this monitor! I don't own the 27 inch version but I'd recommend going with either that size or bigger if you can afford it.
