Kesrer01 Full Motion Long Arm Adjustable Laptop Stand - Rotating & Height Adjustable Computer Desk for Sofa, Bed, Office - Ergonomic Notebook Holder for Work, Gaming, Study & Relaxing

I rarely write reviews, but I sure read a lot of them. I was so particular about this purchase it had to be just right for my new $1000.00 recliner. Nope, the instructions were not in English, but it was a breeze to assemble. Yep, sand was difficult to get in, but the weight of the stand is just perfect. It is just sturdy enough. It is absolutely perfect.The black molded plastic is hollow with a rubber plug to cover a hole. Some one on You Tube was unhappy about the plastic container leaking. Base on the You Tube video I filled container with sand. It takes about 25 pounds of sand. It takes forever to get the sand in with a funnel and a quarter of a cup of sand at a time. It’s not easy to get the plug in the filling hole. I’m concerned about the structural design. It’s hard to move on a rug. I think over time the structure will weaken and fail. The whole vertical structure is held in place by the metric equivalent of approximately 5 number 6 screws that are about 2” long. They screw into pre-threaded holes in the top and bottom of main column. I’m very careful when I have to move on the rug.We bought two, one for myself and the other for my wife. What a journey.Firstly, most holes were not threaded properly, some holes weren't at all. The build quality is sturdy, but what a pain.Secondly, there is no English instructions included. I wound up using the translate app with Google lens to see the instructions.This thing is great to use, but quite a pain to get in and out of a good position. Once you get used to it, it's better, but I certainly would never paid this much for what I received. You'd expect for how much money it was to be of good quality. But here we are.I was expecting up to 20 pieces that I would have to put together by deciphering some convoluted pictures. Well although the instructions are in Chinese and you really have to take a minute and look closely at the pics, the total number of parts was only like 8 pieces and went together pretty easy. If you plan on using sand, like I did, I suggest that be step one. After putting the stand together I put it right to use. I have a 17" 6lb laptop I threw on it. Adjusting the arm couldn't be easier. Using one hand under your computer you take your other hand and push up on the locking knob. Once unlock you just guide the computer to the height you want. You and the powerof gravity guide it right in. Up until now there hasn't been a stand that could handle this huge gaming laptop. The stand is very versatile and can accommodate limitless positions. Tall enough for you to stand up and work, adjustable enough so you sit on the floor. It's amazing. At least for me it's the best stand I've ever had. A quality product. Ironically as I'm writing this, my second one just arrived! Time to get to work.So all-in-all this is really awesome minimalistic mobile desk to have, and surprisingly very hard to find anything quite like it. Feels sturdy and stable enough to not be worried that the laptop will topple over. I actually accidentally hit it once when I got up quickly from the chair and it didn't move much. Few annoying things though:1. Assembly is not well explained. Still got an extra gasket and bolts I have no clew how/where they supposed to go. Also some rubber piece fell off during unpacking and no idea where it belongs. General craftsmanship isn't very high quality.2. It locks ok on the way down but has freedom to move on the way up. Should have been locked both directions and released by lever only when needed adjustment.3. The wheels are cheap and flimsy. I expect those to be first thing wear/break.But it does it's purpose and adjusts to a vast range of heights and distances so I can easily switch from office chair to bar stool to sofa to bed and this will allow me a perfect position at will. Hopefully they will improve it in the future iterations.After my frustration at not finding an essential piece for assembly (the plug for the plastic weight container (for water/sand) and realizing that there were no assembly instructions in English (Chinese only), I decided to give it another go after a good night's sleep. Turns out that the plugs (there actually was a second one for another part) were not in the small parts bag, but floating around in another, unrelated, box. I followed the pictures on the Chinese assembly sheet and, with a couple of missteps, was able to complete the assembly. I made the extra effort because I couldn't find any other laptop device that came close to the features on this one. I put my laptop on it and put it through its initial paces and it looks like it has the flexibility that I am looking for.Assembly was simple. Hardest part was pouring all the sand into the base. I still haven’t finished. Theres a rubber stopper that plugs the hole, doesn’t exactly fit but no biggie. Well balanced once you fill the base.I got this stand so that I could put my laptop on it for use while sitting on a recliner, thus minimize how much lifting I had to do for a bad shoulder. It does a great job. The only improvement I could suggest, would be to make it easier to move side to side. It moves up and down well, but the legs (with wheels) are kind of hard to move on carpet. It isn't that big of a deal for me and the way I am using it.
