FSR (Forged Side Relief) forging designs feature a reduced skirt width and shorter wrist pin when compared to traditional "full round" style forgings. The narrow skirt helps minimize piston contact with the cylinder wall that can cause friction and power loss while the shortened wrist pins reduces the overall weight. Some FSR forgings feature internal and external bracing to provide a more rigid construction while minimizing overall weight With thousands of race miles logged in the most demanding applications like NASCAR, NHRA Pro Stock and Indy Car, these pistons provide the ultimate combination of low-friction, lightweight design with increased stability and strength.

Finally a dual vertical stand with a stable build, quality materials, and snug fit for MacBook Pro
Color: Black Walnut, Color: Black Walnut
I don’t normally write reviews but I’ve had so much trouble finding an adequate vertical stand for two MacBook Pros that doesn’t worry me every time I look at it. I can finally say with confidence that I won’t need to replace this one. Not only is this stand attractive, it is simply a lot more sturdy than the all-metal “industrial” stand that it will replace because my MacBooks fit into it without wobbling, it has a wide surface area base, and its overall fairly heavy due to a solid wood + solid metal build.
This vertical stand stands apart in the two areas that my previous two stands have failed at:
1. A snug fit with a protective lining so that the laptops don’t wobble and bump into each other (the dual Omoton I have suffers from this terribly where the laptops bump and lean against one another)
2. A solid base with enough weight to prevent the stand from tipping over from an accidental bump (my single-laptop human centric mount is beautiful, but the base is too light and narrow so that any decent contact feels that it might tip over)
This stand has a very solid build quality with a nice weight to it which is comforting when potentially storing two expensive pieces of hardware in a vertical orientation that lends to tipping over (MacBook Pros are absurdly well over $2k a piece now on average). This is now the third vertical stand I’ve purchased for my two MacBook pros (work & personal). It’s not my third because I compulsively purchase things I don’t need (though I do do that), but rather because the previous two models felt unstable and carried a greater risk of damaging a few thousand dollars in equipment.
Anyway, this is my first purchase from this brand but I highly recommend!

Amazing! I work off two laptops and this keeps them organized and aesthetically pleasing. True to color. Super sturdy. Doesn’t slide around. Shown in pic on far right.

Perfect for laptops, tablets, Remarkables, Kindles - you name it! This dock is perfect!
Color: Black Walnut, Color: Black Walnut
Coming across UPERGO has been a blessing. To find items of this caliber without having to pay a mortgage payment on it is a lifesaver. It truly is, and I have found that based on my desk setups in my office, UPERGO has not let me down with any of their products. I had already previously owned a UPERGO Vertical Laptop stand. I use that one for my productivity desk for my work laptop and my personal gaming laptop. So, I knew its quality was legitimately top notch already.
The problem I ran into was a workflow issue. I have four portable devices that I carry every day at some point: Microsoft Surface Pro 13", Remarkable Paper Pro, Remarkable Paper Pro Move, and a Kindle Colorsoft. The problem is that I did not want to keep them inside the desk drawer that I use. So, I need something to help save some space on my desk and sort of dock these items when there were not in use. I set one on each opposite side of my desk and that worked out perfectly. I was able to save desk space but also add a bit of protection for these devices. I could adjust the slots, if needed, but it worked out just fine. And the material inside gripped these devices perfectly.
Once again, UPERGO has been able to build a product that fit ideally into my use-case. This time, albeit in a slightly different manner, but it was exactly what I was looking for.

Surprisingly Amazing!
Color: Walnut, Color: Walnut
I bought this expecting it to be a cheaper product I would use until I bought something better. I was very surprised to see how nice it was! Very solid and non slip surface on the bottom. The wood on it looks great and one of the most awesome things about it is you can manually adjust it to fit your laptop. I have a heavy16 inch MacBook Pro with a case on it and it fits perfectly in this stand, after adjusting it, of course. I ended up buying another one for my work office too. I can’t wait to try other products from this company.
