By the way the square shape will give better water coverage than the same size round.
I originally had a round one and prefer the square.
I did have to return it due to an LED problem. A very painless process and didn't cost me anything and happened quite fast considering the distance. Customer service was excellent.
Have never had a problem with all the things I purchased. Watches worth the asking prices.
Good people to work with.
