Overview:
Hays Twister Full Race Torque Converters feature a custom designed anti-balloon plate to stop any converter ballooning and swelling in racing situations. These torque converters are designed for use with a trans-brake and great for power adders such as nitrous, superchargers, and turbos. They are available with various RPM stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss.
Features:
- All Full Race series converters are built, tested, and proven to support up to 1,000 horsepower
- Features a custom anti-balloon plate designed to stop potential torque converter ballooning
- Designed to handle the extreme shock and abuse of trans-brakes, nitrous oxide, superchargers, and turbochargers
- State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
- Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
- All Hays torque converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
- Heavy duty Torrington bearings are used for greater strength and durability
- Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
- Increased horsepower and acceleration due to a weight saving, one application design. Almost all Hays converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
- Full Race series torque converters are offered in several different stall speeds for popular automatic transmissions
- Industry leading Tech Support Team is available to provide assistance with stall speed selection

Works fine overall, but... "you get what you pay for"
Size: Width 16.5", Fully Adjustable Desk Mount, Style: Single
Filed under: "you get what you pay for"? I like the price point and FOR THE MOST PART this arm is getting the job done in my home office space *but* a few points...
(1) The little "claw" to hold the laptop in place has these little "locks" that are on the under side which... that's OK but they can be hard to see and it just seems like an extra part that can break -- vs. a ratcheting clamp.
(2) The tension on every movable part was ALL out of whack when I first installed it. I set the laptop onto the cradle and it basically collapsed -- flipping down as far as it would go. I had to adjust the tension to be significantly higher in order to hold steady -- but NOW it's hard to "fine-tune" because the tension on that joint is so stiff. On the other hand, the main "elbow" joint is easy to adjust *and* holds steady all day, but within seconds of taking my laptop off of the arm, it springs up -- sometimes rather violently.
(3) The overall build quality seems a little weak. The main screw to hold the laptop stand in place had a little cap to make it easier to twist it by hand -- but this snapped off during the initial installation. Not a deal-breaker because once it was in place, I didn't expect to move it again BUT it was still disappointing.
(4) Not a deal-breaker for me BUT... there's practically no included cable management. Just... be aware of that.
Otherwise... instructions were pretty clear vis-à-vis how to install and -- like I said -- it seems to be getting the job done w/r/t/ getting the laptop up off the desk and MOSTLY aligned with my other monitors.

Superb quality. Couldn't be happier.
Size: Width 14", Adjustable Desk Mount, Style: Dual
I have been looking for a separate monitor and laptop stand for a while now and recently came across this set up from WALI. For under $50, I was a little nervous about the quality before it arrived. I had no reason to be concerned. It is a SOLID set up. Everything is high-quality metal construction and secure when assembled. Set up took some doing but only because I am not the most, um, detailed direction follower...Make sure you tighten the tray and post screws TIGHTLY initially to prevent any kind of movement after you've assembled it (don't ask me how I know).
I have a 15'' Asus laptop and the lip on the tray holds it fine as long as I don't tip it too far forward. But it's an unusually thick laptop body so I imagine most won't have an issue. Again, it's not a problem for me at all, just limits slightly the angle I can tilt the tray.
If you are ok with the configuration shown in the primary product image (i.e., monitor above tray) then it will be no problem as is. My desk isn't that deep so I had wanted them to be side-by-side. I was able to set it up that way out of the box. But my monitor was just a hair too big and it cast a shadow on the laptop monitor in the side by side configuration. Support was kind enough to send me a second base post and screws so I could use the grommet and clamp bases at the same time (as is you can only use one or the other). This of course only works if you already have a hole in the desk (or are willing to put one in yourself). Many thanks to WALI's support crew for accommodating me.
I use a standing desk. If movement while you type is something you're fussy about (I'm not) note there will be some shake, especially in the standing position. But for most, it should be absolutely no problem.
Overall a fantastic deal. Highly recommend it!

A Powerhouse USB Hub That Handles Everything I Throw at It
Color: Gray
I’ve been using this 17‑Port 96W Powered USB 3.2 Hub for a few weeks now, and it has completely streamlined my workspace. With 10 USB‑A 3.2 ports, 2 USB‑C 3.2 ports, 3 QC 24W fast‑charging ports, and an SD/TF card reader, this hub truly replaces multiple adapters and dongles. The 10Gbps transfer speeds are legit — large files from my SSDs move quickly and consistently without random disconnects.
The 96W power supply is a huge plus. Even with multiple external drives, peripherals, and a webcam connected, everything stays stable. No flickering, no dropouts, no “device not recognized” issues. The individual power switches are surprisingly useful too — I can turn off specific drives without unplugging anything.
The build quality feels solid and premium. It doesn’t slide around, and it stays cool even under heavy load. The SD/TF card reader is fast and convenient for photo/video work. The QC fast‑charging ports are also great for topping up my phone or accessories, though they’re charging‑only (no data), which is clearly stated.
If you’re someone who uses multiple devices — external HDDs, flash drives, cameras, microphones, card readers, etc. — this hub is a game changer. It’s perfect for PC setups, content creators, IT workstations, and anyone who needs serious connectivity.
Overall, this is one of the most capable, stable, and well‑designed USB hubs I’ve used. Absolutely worth it.

Need lots of connectivity + charging. EXCELLENT.
Color: Gray
Problems with my original USB hub required something better. This unit has allowed me to connect all my peripherals to my laptop and I haven't had any problems with the USB port reliability I was dealing with. I'm using two hubs in series and now everything is working perfectly.

Yes, I wish I'd bought this on Black Friday, but still no regrets
Color: Gray
If you use a lot of add-ons like I do you won't regret buying this hub. The number of connection PLUS high power charging ports works for me. Printer, scanner, mouse dongle, phone, tablet, external drive, flash key all connect with zero problems to my Win 11 laptop. Saves my laptop ports from wear and provides a central location for charging my stuff. Solid metal construction, touch switches for each port, even slots forSDd and micro sd cards makes great design and features. Had a decent usb 3 hub but this one SO much better, good value
