4 x Heavy-Duty & Easy-Open Latches

In order to maintain the case’s airtight and waterproof seal, we utilize a heavy-duty 4 point latching system.

    The add claims the case can fit a 15 – 17 inch laptop. Scroll down the page to product description and it advertises a different claim in two locations as in one of the two seen below. ??? I received the case today and noticed it does not appear to have a tight seal near the handle as the case is a little bowed. I hope it seal and functions as advertised. Otherwise it looks good.Product descriptionCASEMATIX Rugged 15.6” – 17.3” Custom Gaming Laptop Case for Acer Predator Laptops – Does Not Fit Acer Predator 17

    Case seems sturdy and has a lifetime warranty per product description. Was the only case that I could find for the Acer Predator Helios 500. Using some other packing material I had, I configured the bottom to hold the power adapter, portable DVD/CD player/recorder, and mouse. The laptop fits on top; the case closes with no issues. Will post photos later.

    This is a great case I really love it but only problem is hairline fracture on 2 of the latches make it tight to close it probably was my own fault from the top layer of the accessories make it hard to shut a little bit

    OK this definitely fits the ASUS ROG G74Sx, And while it is a very heavy laptop and makes it much easier to carry then in a backpack.


  5. StanC

    Perfect for protecting my laptop. It would be better if it had internal pockets or sleeves.


  6. Jack

    This is a BADVSS laptop case. I would trust tossing this down the stairs with my laptop inside, if that wasn’t inherently just a bad idea. Locking clamps feel very secure, extremely durable plastic build. Fits my laptop and the big Acer block charger perfectly. Highly recommend this case

    Space 4/5Bought this to protect my Acer Predator Helios 300 (2019). It has just enough space to carry my laptop, charger, cooling pad, gaming mouse, and wireless Xbox One controller. To accommodate the thickness of the cooling pad, I actually place the laptop into the case on the cooling pad, just like if I were using it on a desk. With all the foam inserts (case comes with 3) removed, it fits perfectly snugly with the lid closed. The extra space around the laptop (it’s a 15.6″) is where I store the other gadgets and wires. If my laptop were any larger, my configuration wouldn’t work, so beware if you’ve got a 17″ laptop and a bulky cooling pad.Protection 5/5The reason I went with this case was because I travel a lot with this laptop. The rigid plastic exterior protects from sharp objects, while the generously padded foam interior absorbs blunt trauma. There is a rubbery gasket around the lid of the box that mates with the bottom, making it very resistant to water. I wouldn’t toss it into a lake, but I have absolute confidence it would protect against even the heaviest downpour for hours. The hinges are sturdy, and the FOUR latches lock down securely, so there is very little chance of this thing opening unintentionally.Weight 1/5This thing is heavy. This was not a problem for me, because I bought it knowing it would be heavy, but it’s worth mentioning for someone who intends to lug this around all day. I generally take the laptop to and from my car, so the weight doesn’t bother me, but if I had to move around a school campus or something, I’d definitely get a different case. Plus side: if you were attacked, you could probably bludgeon your attacker to death with it, and still have a working laptop after. (That’s a joke, I don’t actually advocate using the Casematix Laptop Case as a self-defense weapon)Overall 5/5This case does everything I wanted it to do with flying colors. Weight was not an issue for my usage, and it has exactly enough space to carry my usual kit. At 1/15th the price of my laptop (or 1/17th if you count taxes), this thing is a bargain for the protection it offers. Bonus: You look like a secret agent walking around with it.

    its everything you would want and need in a sturdy, durable protective case for a laptop. I’ve taken it on many flights and it always keeps my laptop and its accessories in tact. there’s plenty of extra space on the inside of the case for items like headphones, a mouse, Ethernet cable, heck even a keyboard! my laptop is 15.6 inches. and with the extra foam layers included in the case, you can safely separate the laptop accessories from the laptop its self. I haven’t gotten a scratch on it yet. not to mention the whole inside is padded! the only thing I wish I had known was that it tends to create a negative pressure on the inside of the case on flights, so you should definitely unscrew the air cap located near the handle of the case when getting on a flight.
