This silicone case is perfect for handheld GPS devices! Based on our own experience, it fits securely and provides excellent protection for the electronics. the material is durable and easy to clean. The case even has a non-slip surface, making it easy to hold during outdoor activities... However, the only con we found is that it can be a bit difficult to attach and detach from the device. Overall, a great product for anyone who wants to protect their handheld GPS!
