Review on TWIST Bottle 600 & Uni Base Set - Magnetic Bike Water Bottle Holder with Attached Bottle - Cage Free Rack - Clear by Deron Gilliam

Great product if you need to securely mount your bottle somewhere other than regular bolt on cages. I use it on a folding bike where the only tube is practically parallel to the ground, with the unfortunate result that normal cages can't hold the bottle securely and every bump you hit will throw the bottle out of the cage. Very annoying to stay dry during a long trip without water :-( So this is a very useful accessory and I'm glad I have it. However, very expensive for the functionality it offers.
