With Magma your get what you pay for, a strong durable case that hugs the device inside and protects it from bumps, light weight and strong. Have purchase 1 for each of my 3 controllers. Highly recommended.

Protects my prime 4 perfectly and light but robust

Perfect semi hard case makes it easier to store or carry around

This is an excellent case for the Denon Prime 4 Even though it looks flimsy the case is hard like some suitcases Zipper is very good and you can tell its not going to break for some time The padding on the interior may need some trimming but using a hot knife it cuts like butter Im extremely happy with this case
