We use the classic, but to be fair the russians did manage to destroy one completely lol
They made it leak by piling up shavings until they reached the spout and somehow rusted the ball bearings. They did the same with some other bottles but all the rest were fine as soon as we moved them higher up.
Have got nine bottles of that type in use at the moment though (including the replacement for the one the russians wrecked lol) and all are definetly fine. No leaking, no dripping, is all good for all of them
