Review title: Needs only a slight modification to make it great
Product review: It is VERY tight over a 2" ball. It slips on easy, but the vacuum it creates coming off makes it very difficult to remove. You can eliminate the vacuum effect by taking a power drill with a very small bit and putting a couple small holes in the side right near the top...this allows air to come in when taking it off and it comes off as easy as it goes on! I fought with it for months until the light bulb went off and I drilled the holes. With this minor modification it works great. Don't know why the manufacturer has never thought of it!
