These are 3D printed parts. I fact not disclosed in the description.Given that someone designed this product I give it ⭐. Mainly for lack of any imagination. With very little effort these brackets could be made much more versatile.Other than my opinion. These do work as described.I have a few of these on an Uplift desk. They fit between the frame bars on the underside of the desktop, so I use them inside that space to hold three monitor power bricks. I have another near the front, holding a powered ethernet switch under the desk near the front. They feel very sturdy and the adhesive is very strong. Just a simple product, but great quality.Looses position as adhesive not greatThis was the perfect solution to mount my Dell XPS 13 under my desk. The plastic is sturdy and the size was perfect to hold the laptop safely, while still allowing me to access all of the ports and remove the laptop easily when needed. While working at home, I use an ultrawide monitor exclusively, so it was important to be able to stow my laptop, while connected to the monitor, to free up desk space. This was the only solution I found that suited my needs. Because the bottom of my desk is made of particle board, I knew that no screw-mounted option would be stable. The adhesive on this unit is STRONG. Take them seriously when they say to measure and test-fit before removing the strips on the adhesive. If even a corner of the sticky touches a surface, it's permanent. Definitely no way to reposition. I went with their advice and gave the mount 72 hours of curing time before I put the laptop in it. It has been holding tight for a month, even with a warm laptop in it 24/7. Great product!The adhesive gave in after a few months. I used the pair to support a Verizon modem.I got this to get my blue ray player off my desk space. It was easy to mount after measuring the width I needed. The adhesive material is really quite good. Just make sure you have a clean, smooth surface to mount to and you won't have any issues whatsoever.So far my blue ray player has been mounted for about 2 months without any issues.Holds up my laptop power brick just fineI followed every instruction, and waited the full 72 hours before putting any weight on it. It looked and felt pretty sturdy, no flex or reaction when I put my Macbook on it initially. Fast forward a few days later, I hear a crash and go to see the product failed and my Macbook was on the floor. Extremely disappointing, I thought since it was $17 for a small piece of 3D Printed plastic that the adhesive would be strong enough to support a 2ish pound laptop. I was wrong, and hope other people avoid this so it doesn't happen to themI used this to mount my Arctis controller under my desk, the thing barely has any weight to it at all but these have managed to drop it three times and I've only had them a week.I've ended up just resorting to double sided tapping the Arctis to the underside of my desk, works much better so far.Adhesive issue aside, they're about as good quality as you expect from something 3D printed.The brackets are actually adequate but the adhesive pads don’t last long, aren’t very strong and generally render the brackets useless.Unfortunately this product is useless. I followed the instructions and left the brackets for 72 hours before mounting the laptop. I thought great ! Then the laptop crashed to the ground as the bracket had come unstuck. Now I have a damaged laptop. Still need to use this so I have drilled holes through and mounted using screws. Don’t buy it you treasure your tech!Couldn’t manage the weight stated, ended up falling off after about 4 weeks.Product didn't hold my mini laptop and fell multiple times, even though my laptop was under the weight limit by 2lbs. Over priced for a 3D printed product any other metal alternative which would be screwed in would be much better. Don't waste your money
