5.0 out of 5 stars Premium feel and solid protection

P.S. · 20 May 2025

Put this case on the day it arrived and haven’t taken it off since. It’s super sturdy and fits really well. You can tell the quality is very premium the moment you hold it. Its easy to install, not heavy, feel is amazing.What I really like is that it keeps the joycons protected which helps avoid stick drift. That’s actually why I left the original case behind. This one just feels a lot more secure and better built.If you care about keeping your Steam Deck safe and want something that looks and feels top quality, this is a great pick. Love it.

5.0 out of 5 stars Great case for full coverage

U.N. · 28 June 2025

Very good case for the price, provides the entire steam deck with protection, fits perfectly around all ports. Slipping the deck in can be tricky if you have custom triggers at the back but you can angle it in to make it fit. The cover stays firmly attached allowing you to throw it in a backpack. The accessories are good quality, the battery pack strap is long enough for most powerbanks. Although it says its not compatible with the jsaux custom backplates, the hole that the accessories attach to is over the top of the vent, so it doesn't really obstruct it.

⭐⭐⭐⭐⭐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!

4.0 out of 5 stars Very good, be careful putting it on/off as you may harm your deck.

I had a lot of trouble getting the back cover on my OLED. There is no give in the hard silicone and it was putting a scary amount of pressure between my triggers and the back plate when I was putting it on or off.The stand is the most important part of this cover for me, and it is wonderful. It allows me to use my steamdeck like a tablet or switch. I like to play with it on my desk, with a controller. This is better than holding it mostly as your hands will feel very uncomfortable holding the deck for a long time, especially with the heavy silicone jacket on.The case looks good on the steamdeck. The buttons at the top work perfectly, making them much easier to press than they are on the unit itself.Applying the front cover is simple but the unit doesn't have any water protection. I would not put it in the same bag as any water bottles. It does, *somehow*, fit into my Tomco case with the protective faceplate on. So if you want extra weather or dirt resistance, you can double team it with an alternate case. For the most part you'll be using this modcase for its mods and drop protection rather than as a carrying case anyway.

5.0 out of 5 stars Well made, fits official valve dock, bit heavy at first but can remove mods to fix that.

Just got this, review is tentative depending on whether it lasts.So far really good case, feels heavy when you first put it on but that's with kickstand and strap attached, removing these felt lighter than other cases I've used. The strap doesn't weigh much but the kickstand is pretty heavy, though it pops off pretty easily and I imagine I won't use it much.The strap is great for letting you hold the deck more like a tablet and use the touch screen more, which is why I bought this case. The front panel pops off easily and feels super durable when it's on, you can't press the sticks at all and it has a cushioned panel inside it to prevent screen damage.Also, really nice surprise, it comes with an adapter for the official dock so you can still use it with the case on, and the case is cut so the official dock's usb-c connector isn't blocked.Complaints: Really wish it came in different colours, and attachments are pretty limited. Compatible phone holder would be awesome.

Before I write my actual review I want to comment on something I've read in a few. A few people have mentioned a "flimsy rubber stand" in their reviews. It isn't actually a stand. Having looked at it, I realised it looked like a cover for a Dock, when I checked the box, it does list a "protect case for dock" (I'd assume a JSAUX model), it's a nice extra addition so you can place your Steam Deck on the dock with the case on. Most docks appear to be far too narrow, so this would have been a real bonus. I'm not sure why JSAUX don't mention it anywhere on the listing. I personally ordered the Mod Case with the attachable Dock, but... If I had known the case came with this piece, I probably would have opted for one of their stationary docks. 🤷🏽‍♂️Now for the actual review...The case is amazing. It feels solid and fits incredibly well, without restricting use. It adds a decent amount of weight to the deck, which I personally really do like. I'm quite tall and have big hands, and the added weight is just makes it feel more solid.As someone with big hands, the Steam Deck (without case) isn't the most ergonomic. Playing with the case on felt a lot more comfortable.The front cover is great as well, and padded, for the extra protection whioe on the move.The kickstand is also nice to have. It's solid metal, attaches firmly, and does not get in the way of play. I've used it when putting my Deck down to charge.The dock also attaches easily, and keeps the case standing well.I haven't tried the battery pack strap yet, but if the quality is comparable... I can't see what could go wrong.Easy 5*

Super qualité, super pratique

C’est super pour mon steam deck, ça protège bien, ça ne le rend pas plus “bulky” et la petite béquille est top, j’aime aussi le fait que seulement le dessus s’enlève donc hyper facile à ranger dans un sac.

Semplicemente perfetta

S. · 26 August 2023

Cover perfetta, calza perfettamente sulla scocca originale lasciando liberi i controlli, la copertura è sufficientemente rigida da proteggere lo schermo anche da colpi abbastanza forti (ha anche un cuscinetto morbido che separa la cover dallo schermo). Ottimo il grip, la vera sorpresa è la ventola che abbassa di 10-15 C le temperature in game. Raramente ho visto un accessorio non originale con una qualità simile.

Super accesoires.

Exactly what you need for Steam Deck

This set can easely replace docking station and make it portable. I also have JSAUX dock station, so i don't need it anymore.

One of the Best

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!
