This isn't a big deal, but instead of sitting flush to the deck, gravity pulls it down about 1cm away from the back of the case. This doesn't appear to affect the kickstands ability when you are actually using it though.- The trigger buttons are still slightly exposed. I feel like this is one of the most common negatives I see for this case, but honestly I am not convinced it is actually THAT big of a deal. I definitely would not feel worried at all about the triggers if I was just throwing this into a bag (I use a bag with a dedicated Steam Deck slot though so this is even less of a concern for me personally).- I don't know if this is a good thing or bad thing, but the front case is a little awkward to get off because it sticks to the front of the deck so well. The way I end up taking it off, is resting the deck on my lap and then holding both ends with my fingers and using my thumbs to push the front case up and off the deck. This can sometimes end up with the front case flipping up and away from you so you have to be careful not to fling it on the floor.The good things:- Everything feels study and the fit is fantastic.- It doesn't feel bulky at all and when I am using the deck you don't even notice that there is a case on it.- The front cover fits really well and is very study in place. Absolutely no worries that it will accidentally fall off, the analogue sticks are well protected and so you don't have to worry about them breaking in your bag from being pushed and held in one direction. The triggers are also really well protected, even if they aren't completely covered.- There is a cut out for the charging port that allows for those 90 degree angle charging cables to be used. Or just about any charging cable you have really.The kickstand works really well and it feels nice and stable when it is resting up. There is only one angle you can set it to, but I feel like it is a decent angle personally.- The volume and power buttons are covered up for protection but easily able to be pressed.- The accessory I got to hold a power bank or similar on the back of the case works really well. I tested it with my INIU 25000mAh power bank and it holds it in place well and feels nice and safe. The fastening can be a little fidgety but it gives me more confidence that they will stay in place as a result so I guess it is a positive rather than negative.I cannot test the cover that came with it for a Dock, because I don't have a dock to test it with, but I assume based on the rest of the product that this is also good quality.Conclusion: Overall, it is pretty close to perfect in my opinion. It is a lot cheaper than the Killswitch case which is the other major one that most people recommend, and I don't think there is likely to be much difference in quality (It sounds like the Killswitch case will be marginally better, but it is also more than double the price)If you want a good quality case but don't want to break the bank, then I highly recommend this case. ### ⭐⭐⭐⭐⭐ Great case and travel cover *by on Reviewed in the United Kingdom 4 June 2026* This is an excellent case, it fit very nicely; the slight bulk on the grips makes it much more comfortable to hold and the back buttons easier to press. The stand is excellent and feels very premium. My only complaint is that the power button is exposed while the screen is covered so if you're deck is jostled it might get powered on by accident. Overall great value for money and it looks great. ### ⭐⭐⭐⭐⭐ Brilliant Gadget for Steam Deck (OLED) *by on Reviewed in the United Kingdom 30 December 2024* ⭐⭐⭐⭐⭐Best Case for Gamers and Tech Enthusiasts!The JSAUX ModCase is an absolute must-have! The modular design is genius, offering unparalleled versatility. Whether you need extra grip, a kickstand, or dock compatibility, this case has it all covered. The fit is perfect, and it feels premium in hand without adding unnecessary bulk to the device.The materials are durable and provide excellent protection without compromising the sleek look. It’s clear a lot of thought went into this design, catering perfectly to gamers and anyone looking to get the most out of their device. I couldn’t be happier with my purchase—highly recommend it to anyone!I wish you could order a portable dock which works with this case. I currently use the strap to hold my JSAUX dock to the back of my Steam Deck, it works, but not perfectly! ## Frequently Bought Together - JSAUX PC0104 ModCase Compatible with Steam Deck, Steam Deck Case Comprehensive Protection Include Detachable Front Shell, Body Protective Shell, Metal Bracket and Strap - Basic Set - JSAUX 2-Pack Steam Deck Screen Protector, Ultra HD Glass Protector 9H Hardness Easy to Install with Guiding Frame Scratch Resistant Tempered Glass for Steam Deck/Steam Deck OLED, Come with Toolkits - JSAUX Docking Station for Steam Deck/ROG Ally/Legion Go/MSI Claw, 6-in-1 Steam Deck Dock with HDMI 4K@60Hz, Gigabit Ethernet, 3 USB A 3.0 and 100W Charge, Compatible with Steam Deck OLED-HB0603 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/511144576-jsaux-modcase-compatible-with-steam-deck-pc0104-modular-valve-accessories](https://www.desertcart.jp/products/511144576-jsaux-modcase-compatible-with-steam-deck-pc0104-modular-valve-accessories) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-12*
