3 Pack for Polar M430 Screen Protector Tempered Glass for Polar M400 GPS Running Watch Screen Protector Foils Glass 9H 0.3MM Anti-Scratch Anti-Fingerprint Bubble Free

Great quality glass protectors that stick really well. I swim and sauna weekly and they don't come off. Easy to apply with all the things probided and are really good value and quality.Why 4 stars then?Good question....they are very slightly smaller than the face. I guess they need to be smaller but there is about 0.5 to 1mm gap top and bottom of actual screen. Now I'm on my 2nd box of these in 3 years so I know they work a treat stopping the watch face getting damaged but it is just very slightly annoying.I would definatley recommend them.

No impressed. Screen protector is about 1mm smaller, around all edges than the actual M430 screen. Makes it really difficult to align correctly.In addition, it cracked within a day of fitting. I hadn't impacted my watch in any way. If it breaks that easily it is worthless. Lucky they supply three protectors - on to my second now after only a few days

A good product easy to fit
