Built like a rock; making adjustments not very intuitive
934912
Built like a rock. My keyboard weighs next to nothing but I didn't want it bouncing around. I have owned older, very heavy keyboards and this would handle any of them without breaking a sweat. Neither the rubber isolation bumpers nor the height adjustment device are very intuitive but if you play with them you can get them right within ten or so minutes and the height adjustment remembers your setting. Aside from the rubber isolators, this thing would last forever and is rock steady.

Wasn't sure how to rate this. The quality is good. The construction is solid. Adjustability is decent. But it doesn't so much function to keep back straight which was what I thought I was getting. I tend to get pain in my spine that "alleviates" if kept straight. The seat portion is excessively looooooong, not allowing for spine to adequately contact the back portion of chair to stabilize and keep spine aligned. Even adjusting its back to the forward most position was not enough. The seat is pretty wide, too. And I'm portly @ 5' 7" and 230, but this brother's butt was still excessively small compared to seat. Perhaps if you have squatch-sized femurs you'd be okay, or you're not looking for spine straightening support.

I've had this chair at work for about 3 years now. I'm a computer programmer and sit in this chair for almost the entire 8.5 hours that I am at work. I have tried to get the difficult adjustments right and I have played around with them a lot and, no matter what I do, I can't get it to a position that's comfortable. Depending on the day, sometimes it ranges from noticeably uncomfortable to downright painful. The maximum tilt back position is a joke. I feel like I'm sitting straight up as opposed to being tilted forward otherwise. Reclining is just not possible in this chair, so even if it weren't uncomfortable, it would not be appropriate for home use. The left and right movement of the arms is incredibly annoying as they just move wherever with very little pressure. The lumbar support is a pain to get adjusted. I am 5'11" and around 175Lbs for the record.

Sometimes hard to figure out. Controls are awkward.

Well built but tough to get together straight and solid.

I give 3 star rating despite its superior performance because of its design. ViewSonic should know that this product is extremely hard to learn to navigate and adjust the setting of the monitor. I bought it new, and there is no instruction of adjusting settings in the manual. I was very frustrated for at least 15 min straight because I did not know how to simply adjust the brightness. Also, the location of the buttons are very inconvenient. I have to lay my head on the table in order to see buttons to press. Nice time hugging the table thanks to ViewSonic.

The adjustment screws are located on the wrong side which makes it hard to adjust it. The bottom plate makes it too shallow for some rods.

Requires frequent re-positioning of the front dial as barometric pressure changes.  There is also a screw adjustment on the rear to recalibrate barometric pressure.  Maybe the frequency of adjustment required will become clearer  as I use it more.  Seems well built.

Threads on one side of the wrench thing were messed up out of the "bag", so adjustment is very clunky as the nut grinds against the screw. It will adjust, but only after fiddling with it, etc. Barely tolerable for the very occasional use I have for it but not worth my effort to return, etc. given the price and frequency I am going to use it.

Takes some practice. Not as easy as it looks

Always need adjustment, like leveling the legs.then your butanin'.

The mechanical design here is actually fairly clever; simple, compact, adjustable. The fatal problem lies in the round metal rails that run within the aluminum  u-channel extrusion; mine were not exactly parallel. That meant it was impossible to adjust the trolley wheels for the whole track; it was either lose on one side or bound up on the other.

Furthermore, there's such little clearance under the trolley that without those wheels perfectly adjusted, it would contact the bottom of the track and bind. If I pulled the trolley upward, or turned the whole thing over so it was hanging, it moved freely enough to slide with just a little tilt. But given the track width variance, I couldn't adjust this problem out...so back it went.

I can't figure out why those round rails are there at all...it would seem simpler, lighter, easier to manufacture and less error-prone to just design the rail profile into the aluminum extrusion itself. If you guys at Neewer read these things; fix the track and this'll be great; i'd keep one in my tripod bag (they're that small)

Not bad but I wish it could be adjusted a bit

I really wanted to like this thing but could not get it work as smooth as I would like it to. They said you need to use it a while and get the hang of it but I never could get it to stop rocking side to side when I walk. Maybe it's the way I walk, I can't walk with a stack of books on my head either. Also the wind really affects it. It keeps wanting to turn sideways with the slightest breeze. It is also not something I would walk down a crowed street with. I'll sell it cheap if anyone is interested. I ended up buying a battery powered, 3-axis, hand held gimbal and I love it.

Structurally solid, but a real pain to install as the female side of the nuts is not captured in the female side of the adapter (like they are in the actual holster), so it spins as you try to screw it together with whatever holster mount (drop leg, paddle, belt loop, etc).  Also, it adds about half an inch of standoff to the overall setup.  Not a big deal on the very solid setup of the drop leg, but feels very bouncy with a paddle.  Finally, it does not index correctly.  Putting it on the paddle mount, I could not get it to index straight up and down, it either had a forward or backward cant.  I am returning mine.

This looks awesome on the scope, and would definitely make adjustments easier. I unfortunately couldn't get it to tighten up enough to quit wobbling. Was actually able to slip it off by hand without loosening the mounting screws. Working on finding a solution to that but haven't had much luck yet.

It's sometimes hard to adjust it. Squeeze in one area and open in another until you finally get it so it doesn't slide down.
