I'll make this review short and sweet.

I filled the base with water (I planned to use this in my garage) - then I spent an hour or more assembling this product.  Once assembled, I threw a series of punches ... no more than 5 - 6 ... and the product sheared from the base. The plastic didn't break, however the mount is attached to the base via two vertical screw-in plastic poles.  Both screw portions of the mounting poles are glued.  The glue failed, allowing the top of the mounting pole and the heavy bag to fly 5-6 feet across my garage and into my Harley-Davidson motorcycle.

Bottom-line: This product is cheaply made - and is held together by glue in several strategic areas.  It lasted 10-seconds or less before breaking.  It may be durable enough for a child, but I don't believe it will stand-up to any type of regular, adult use.  Like I said, mine honestly lasted 10-seconds or less!

Need I say more?
