Review on 📱 RuenTech Bands Compatible for Polar M400 & M430 Watches - Soft Silicone Wristband Sports Band for GPS Smart Sports Watch Replacement by Chris Cranor

== Original review January 9, 2018 == Repeat many of the following comments: I like that the strap is a bit softer. On the negative side the strap is a bit shorter so if you have very large wrists you have a problem; For me, however, this simply means I'll be using it on the fifth hole from the back. It takes some patience to line up the holes and get the pin through, but I think it's a good thing in the end as it means they're tight and secure. The most important thing I have to add is to make sure that all entry holes on the real watch are free of dirt. As for me, my old strap ripped and I didn't realize that it left a piece of perfectly smooth plastic in the center hole on one side of the watch. This meant I could get one group pretty easily while fighting another for too long. Finally realizing that the hole didn't look deep enough, I started digging in with a screwdriver and eventually pulled out the old plastic. Then the second strap fitted snugly and securely, allowing the pin to slide. == Update Summary March 17, 2018 == I had my original Polar strap for three years before it broke. I had this strap for about two months and the rubber was completely detached from the plastic insert that attaches it to the watch case. I've emailed the company but haven't received a response yet. I would say it would definitely be worth paying more for a group elsewhere. == Update March 26, 2018 == The company has contacted me to replace the strap they sent me. Sent with 2 days free shipping. Now it's a big group, which is nice. Hope it lasts this time.
