Solidly Built
Solidly built. Easy install. Haven't used them on the trail yet but if they work like they look I don't expect any issues.

Good storage for your ATV four wheeler.
Works great. Fits on my 2023 Canam 850 Outlander. I needed a storage compartment where I could put a few tools, gloves, flashlight and straps to seccure my cargo when not in use. It is well built and attaches firmly to the back of my front wheel well body molding. It does not interfer with my driving or leg movement. The only down side when you unzip the lid it doesn't fold back easily but it still excessable.

MEH. Not worth $40
Meh. Not sure about durability for 39.99. Seems a bit steep for what showed up at my door, hence the one star. Opening the top is clumsy and can barely open if mounted against something flat. The cheap strap setup might work in a specific ATV application, but don't buy this bag (especially for 40 bucks) if you plan to try it in any other way. The chintzy sticky velcro pads plus dumb strap and buckle design pretty much rules out clicking the bottom and top straps together for a tidy wrap-around installation. This should've been a $20 item at most.

Awesome
Very sturdy, looks awesome too. I bolted mine to the plastic vs using the straps and it's way better. 4 bolts and 4 nuts and 8 washers is all it takes.
