PRO's: Size, Price, Functionality, Ease of Installation, Appearance, Light WeightCON's: If any, it was my initial take on the up/down function. However, most of my time with adjustable desks are commercial grade electric desks, which is a completely different universe for pricing and functionality. I've figured it out quickly and it isn't too bad, you just need to understand you're manually controlling 2 separate pneumatic (air) driven adjustable legs, so it isn't going to be as smooth as an electric/automatically driven desk. Also, it is likely based on what you have on it, and mine is loaded down with 2 monitors on desk-mounted adjustable arms, plus a laptop.I use this as a computer desk that I can adjust so I can stand or sit, and roll it into a spare room when it is not being used. I have 2 x 24" monitors mounted with adjustable computer monitor arms and hooked up to my Chromebook laptop. If you're using this for a simple bedside/sofa-side desk or just a sitting desk that you can adjust to your perfect height, it will work very, very nicely. If you're going to make it a modern, multi-mounted-monitor computer desk like mine, it will as well, so read on... I mocked up the height I'd need it when standing. I recommend you do that whenever shopping stand up desks. At 5'8" tall, 37"-ish inches was going to be the max I'd need it to be comfortable for me. So this met that criteria by a long shot since it goes up to 42"! It should fit almost anyone as a stand-up desk. I also wanted a desk that was long enough for my laptop with a notebook on 1 side and mousing area on the other, plus a little room to spare on either side. This desk was also perfect for that. I didn't want a wide/deep desk so at 20.5" this fit that requirement as well. The con that I listed as the up and down function is related to the up and down movement. At first I squeezed the handles on both sides expecting it to just pop up on its own. It actually does, but after I give it just a bit of upward pull. But again, I have some weight on it with monitors, monitor arms, laptop, phone with wireless charger usually a coffee and/or water ,etc. A day into adjusting it up and down and I have the process nailed down. It is hard to find a desk this size, of this quality and functionality, that looks this good, at this price. I'm very satisfied with this desk after over a week of use.Installation hint: If the pneumatic up/down function doesn't work once it is set up, you likely put the squeeze handle-arm on backwards. A hint is that when you install it, the balls at the end of the handles on either side should be pointing towards the front of the desk, NOT the back.Tangkula Mobile Standing Desk Computer Desk (black)Sturdy, good looking, relatively easy to adjust. I would buy it again.I rated "Easy to assemble" lower because clearly people are having difficulty with smooth operation. And I had to readjust mine after I had it fully assembled. See my hints below.If you are a 'shorter' person read this... See the dimensions and test if this will work for you; as described, the table top height range is 27.5” to 42”. I wish it was 22.5” to 37”. I am 5'7". I knew this was tall for my ergonomic sitting position to have my feet on flat the floor and 'keyboard just above lap' with right-angle elbows. I'm using it on carpet, so I decided to use it without the casters. It slides just fine that way. Even without casters, it is still a little higher than I prefer but it was this best option I could find -- The surface area fits my needs exactly .Helpful Hints: Others mention that one must use both adjustment levels at the same time to adjust this. A few details to fix this:1. You must install the lever bar in the posts the correct way - look closely at instructions.2 This auto-raises but does not auto-lower, so you must use your weight to lower it. Distribute your weight evenly left to right, across the tops of the posts.3. For smoothest operation: Understand that friction is created on the gas-rod/post edges when the posts are installed with the slighted bend/flex (they must not be stressed out of their natural straightness. To fix this, raise the unit about 50% height then lay the unit on it's back with the bottom (casters) facing you. Loosen the 4 bolts on the gas-posts so that you can freely shift the posts side-to-side. Jiggle the posts so they settle naturally in an unflexed position -- this is the least stress on the internal posts. Tightening the bolts down in that position will provide the smoothest operation. If this naturally unflexed position is pressed against the side of the frame screw-holes, then the post screws at the table-top side need re-centering before tightening the floor side post screws.Love this desk.. read reviews on all desks and settled on this one for the following reasons:Small, movable, air lift height adjust, good reviews. .. assembly questions on reviews such as “leg heights different”.. that is easily solved by pressing the button on the of the leg and apply a bit of pressure to change the height..This is the best.. been using it for 2 weeks now and it’s great.. up/down/roll around.. it’s a great office now that Covid continues to keep me working from home.. was stuck in the office room until I started using an ironing board and moving about as a standup desk .. but I wanted something a bit better and fully adjustable..Thumbs up = good engineering and designI needed a desk with wheels that I can move between my living room and my bedroom/office. It is super easy to move and rolls very well. The wheels lock when in one place. On the top of the desk I have one large computer screen on a stand on the left and a laptop on the right. The size is perfect. There is also about 12 inches in front of the screen of table space for my coffee cup and papers. I also purchased a removable keyboard tray that was easy to attach to the desk. It has a tiny wobble if I push against it but overall it is very stable as I work on a computer all day. It exceeds my expectations and I am super happy with it. My friend assembled it and said it took about ten minutes. It also goes up and down very smoothly, which I actually don't need as I purchased it for the wheels. My legs fit under the entire desk, whether I sit to the left or right. In other words, I can move left to right and my legs fit perfectly. I can also stretch my legs out in front. Highly recommend this product.I have never written a review, but felt like I had to talk about my experience with this item. I would not recommend this product as it was really hard to assemble due to the lack of written instructions in the manual. The legs are different heights and to adjust them, I had to read the reviews on Amazon to figure out how to do so. Thanks to the user who mentioned that you have to use the piece that looks like a “T” to depress the little button on the bottom of the legs. That allowed me to change the pressure of the height of the longer leg (which I was struggling with). After getting the legs at the same height, the table was easier to assemble. However, I still do not like it because it’s also very difficult to lower (you must raise the table first then press down on the handles to lower). Please think twice before purchasing this product.
