Nice tank signaling device, plastic feels durable and hard, strap feels like a silicone rubber, very stretchy. Makes a good ring on tank!
Top of the hill.

1 broke under minimal pressure. The other was ineffective in alerting dive partner as plastic on aluminum tank makes virtually no sound. waste of money

The build is good. looks like it will last, but I just didn't think it made very much noise which is kinda the point
