This is a FANTASTIC case. I take my Steam Deck to work and play on my lunch breaks. I have a relatively small bag, so the full Valve case didn't fit. However, with this case it fits PERFECTLY! With the front cover, it protects it well and I don't have to worry about the screen getting scratched. All the moddable attachments are also really nice to have for an external battery, etc. The stand works super well, very sturdy with no flex what do ever. 8 also have the JSAUX dock that I use at home, and the steam deck still fits in there perfectly with this case on. The grips where you hold the steam deck are very comfortable and don't let it slide out of your hands. Pulling off the front cover is a bit tough, I do wish there was an easier way to detach rather than peeling it off aggressively everytime. But putting the cover on is a piece of cake, the fits are perfect when closing it up. It's relatively thick, which I like. I have not dropped it so I can't really comment on how well it'd protect a dro. I have no complaints what so ever, it is absolutely worth the money!

I'm not exactly rough with my electronics, but when I decided to get a Steam Deck, I bought this as well and installed it the first day I got my Deck. I wanted to protect the corners in case I'd bump something as I moved it around in my hands, but mostly I got it so I could use the attachments and for the protective cover for easy travelling. I also have a dog and cat, so I wanted something to protect the screen if I laid it down, and the plastic cover works perfectly for that! It feels good in the hands. The edge of the case where the palms rest do NOT dig into my palms, and I have pretty sensitive hands. I also LOVE the kickstand. Not only does it prop the system up well and feels sturdy, but when I'm playing games in bed or have a blanket on my lap while playing, I open the kickstand a bit because it's over the fan intake for the Deck. With the kickstand open, it pushes any blankets or pillows AWAY from the intake, letting fresh air in. It's a nice, unintended feature! When I first got it, I would open the kickstand and balance the deck on my desk while I held it to steady it while playing. I DO NOT RECOMMEND THIS! I ended up breaking the kickstand doing this. It was not meant to hold THAT much weight at THAT angle. HOWEVER, I reached out to JSAUX support, explained what happened, and they quickly sent me a replacement kickstand accessory for free! Very quick to respond and act! PROS: -Decent protection -Compact and simple travel protection with the cover, though I wouldn't trust it rattling around in a suitcase or bag. -Great accessories, including the kickstand! CONS: -Don't know how much it will protect from drops or hard hits. -The front cover doesn't protect the power button from being pressed. This COULD be dangerous, because it does cover the exhaust vent. So if you accidentally turn it on and you were in a game, it might cook a bit. TL;DR: Feels good and they have great customer service. Good for daily protections, but not intended for protecting inside luggage or a bag.

This is a great product that works as both a protector for your Steam Deck and a solid travel case. The built in kick-stand is of high quality and feels sturdy. The entire product feels good, was easy to put onto the device and has great feel in the hands, with the grips adding much needed texture that the original Steam Deck device did not seem to have. I can't imagine playing my Deck without this on it now. The cover is great because it's got a soft backing that protects your screen. It's dense plastic material that could withstand some small impact, but I wouldn't go testing dropping anything super heavy on this thing. I used this case to travel with my Deck and it was perfect. One thing to note is that the cover feels like it's difficult to take off, and that is normal. I think that will initially scare people that they have to use some amount of force to remove the cover, but don't worry. It is easy to put back on and stays secure and in place when on. It does not fully block the top vents either, and allows you to continue charging the device with the cover on if you want. Highly recommend every new Steam Deck owner buy this ASAP.
