Great timer. Its sound ("plus" +) is quite loud, but I don't have any other timers to compare. It should also be more water and sweat resistant, but haven't tested the thing yet. The strap is worth it. Update 05/23/19: I've been using this timer for about 6-8 months, about 2 times a week and I can say that it's a great thing! Has held up so far, fairly loud and great for HIIT/Circuit/Boxing MMA rounds.
