I've been using the groove tube for the last couple years, and honestly love it. It looks like a gimmicky golf gadget at first glance, but is honestly a super useful product. I pretty much use it after every swing to clean off the grooves of my clubs and after every hole to clean my ball. The product spends a lot of time getting pulled on and outdoors in the sun, so the rubber ring at the top of the tube can eventually rip or get brittle, at which time buying another one is well worth the purchase.
