KIRSCH Blood Plasma Freezer
The energy-saving KIRSCH blood plasma freezer complies with DIN ISO 13485 and DIN 58375 and is equipped with the PRO-ACTIVE control system which, in addition to permanent monitoring of all performance data, ensures minimal temperature deviations between the warmest and coolest storage locations. At the same time, efficient recirculating air cooling ensures even temperature regulation without strong temperature fluctuations. This ensures constant and uniform cooling of the blood plasma samples.
To protect the temperature control from unauthorised access, it is protected with a key switch or RFID/password, depending on the version. The time-consuming documentation of the minimum and maximum temperature is minimised for the specialist staff, as the freezer is equipped with an integrated memory whose data can be easily read and archived. In the event of a power failure or other malfunctions that may cause deviations in cooling, an acoustic and visual signal indicates the malfunctions. If required, alarm forwarding to a mobile phone, for example, is also possible to receive notification of alarms anywhere and anytime.

Love this chair!
Color: Black, Size: Pack of 1
I had an office chair that cost $300 more than this chair - had it for years, then things started breaking down on it. I read about this chair and, wow! I wish I had known about it sooner. It's more comfortable and it's not a chore to sit for a couple of hours working on designs. Wonderful design - supports my back well and it's very stable, easy to adjust.

Good chair with some quality issues
Color: Black, Size: Pack of 1
I've been using this chair for 12+ hours a day for the last 5 or 6 months and so far it is much better than my last chair I bought at Staples with a few problems.
First, overall the chair is still comfortable when set properly, the cushion on the bottom is a little worn out but is still comfortable and I find the backrest comfortable except for the lumbar support which has very little cushioning and feels like a plastic brick being pushed into my back, however I find that I can keep it mostly out of the way most of the time and it isn't noticeable when I carry most of my weight on my upper back area while reclining.
The reclining angle is super comfortable and the mesh on the back is not noticeably worn out. I like the headrest which is made of a cushioned mesh, its not better than a pillow but it's very comfortable to be able to rest your head in a chair you are going to sit in for long hours and gives good support.
The arm rests don't feel amazing, they have a very stiff plasticky cushion feeling that I'm not much a fan of in terms of pure comfort but they get the job done as I mostly only rest my elbows on them when typing. The arm rest adjustment has a pretty good height range and I keep them at the highest settings and set as close to the chair as possible.
While the chair may be comfortable, I have had some quality issues that bring down my opinion of the chair.
First, my right arm rest does not go as high as my left arm rest and I have to set the left one down two positions to match the right one
Second, the back rest locking for the upright position is broken but I can rarely get it to work as long as I don't put much weight on the back. I would imagine that most people would want to lock the chair upright as opposed to the other positions.
Third, the 3 screws holding in the backrest untighten themselves over time, causing the backrest to move to its furthest back position and rock left or right if I lean on either side. When I tighten them again they will usually last about 1-2 weeks before becoming mostly loose again. There is no danger of the screws completely falling out though, just losing their tightness
Lastly, I'm not sure how stable or secure the wood panel at the bottom of the seat that everything attaches to is strong enough, I used to have my armrests adjusted out further from the center but when I would lift up on my arms to adjust my seating position I would occasionally hear a sound of the wood stressing under the torque from the armrests. since I moved both armrests as close to the center as I can this has not happened; I would like them a little bit wider but I don't want to risk breaking the chair over it. Also, one of the factory-installed screws in the bottom seat panel fell out and wont stay back in but I haven't noticed any problems other than the risk of stepping on a screw caused by it
While this is likely the most comfortable chair I've ever sat in, I have to give it 3 stars for the uncomfortable lumbar support and the quality control issues. If the QC issues were fixed I could easily give this chair a 4 star review

Fantastic!
Color: Light Grey, Size: Pack of 1, Color: Light Grey, Size: Pack of 1
Outstanding quality and incredibly easy to assemble! The back support is a perfect 10/10. I was debating between the M57 and the B100, and the B100 definitely won me over. The materials feel premium and durable. Highly recommended!

Comfortable. Great Value for money. Easy to assemble. Great customer service.
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I've been looking for a new chair to replace a cheap $30 chair i bought off of Amazon last year that had been killing my back and shoulders. I wanted something in the $150-$200 range and settled on the M18. Shipping was a fast 3 days with Prime and the box arrived in great condition.
All parts were separately wrapped or in their own boxes. Came with all hardware and nothing was missing. Assembly took me a little longer then normal because i have rotator cuff injury in my left shoulder so that arm is mostly useless. The most difficult part for me was attaching the wheels to the base. Other then that it was simple.
Once the chair was assembled i sat in it for the first time and started making my adjustments with the recline feature, armrest level along with the headrest. Next i reached around for the lumbar support knob and tried to adjust it but with my bad shoulder i decided to just get out of the seat and turn it around and adjust it with both hands. After spinning the chair a round to get at the lumbar knob i noticed a large crack in the plastic in the middle of the back of the lumbar plastic piece. I had not made any lumbar adjustments yet so i assumed this is how i received it. The lumbar support comes preinstalled to the backrest so it either was damaged before or during the shipping process. Either way it was damaged before being delivered to me. The lumbar support still functioned properly but it was still broken.
I decided to contact Sihoo's customer support that came along with the installation instructions regarding the damaged lumbar piece. I received a reply the next day and after sending them some more info about my order and a couple pics they shipped me a replacement part which took a week to arrive. I swapped out the damaged part and after owning the chair for a week so far i am really happy with my purchase.
Im about 5'10 180lbs. At its highest height level my feet reach the ground comfortably flat footed. The backrest fully covers my back and the headrest adjusts very well to sit on the back of my lower head/upper neck. The armrests only go up and down....not forward and back or tilt inwards. This is fine for me as they are grooved to fit your forearm while sitting at your desk/keyboard. The armrests are also a soft cushioned rubber material...not a hard plastic. The mesh of the backrest and headrest are good material and seem well made. The seat is very wide and the cushioning is firm which i prefer. Usually more firm cushioning seems to last longer and hold its form. The base of the chair is VERY sturdy and made of all metal. My chair is on carpet and holds its position very well. As far as recline goes you can set it to recline all the way back, half way or lock the chair in the upright position. You can also adjust the resistance on the reclining feature.
So that being said im very happy with my purchase. It arrived with a slight flaw which the company corrected in a fast manor and was very polite in their customer support. I personally don't have a lot of experience with many office chairs and have never used a high end chair($500-$1000+) chair before to make any comparisons. All my chairs for the most part have been from local stores like Staples or Office Depot. Id recommend this over anything they carry in this price range....and i went and looked at their products before buying this chair as well.
