works very well. In fact I reordered. You just need to figure out how to remove the plastic covers for extracting the protection film. Once you're already there it's easy to install and stays stuck on your watch. it also matches well Suunto D4 screen.
Bought for Suunto D4 and installed right after the original Suunto protector. It misses about half milimiter for covering completely the entire screen. It's also very stiff making difficult to remove the bubbles.
bubble issue, the screen doesn't stay stuck. let's see when it falls down. Don't buy!!!!
