Woohoo! Just picked up my new wave master bag today!
I was thinking that it might be a good idea to post reviews on home fitness equipment. Let's use a five star rating system, 5=best, 1=worst
[You must be registered and logged in to see this image.]I've used the Wavemaster Bag by Century many times before and for a $99.99 bag (cheap), it works pretty well. I can't hang a bag because I have no where to hang one from, except for places that are in the way. So this bag gives me the option to fill it with sand or water. It can also be pushed into a corner, so it's not always in the way when I'm not using it. The bag can be adjusted in height for your needs.
A heavier canvas bag would definitely last longer, but you'd also be looking at ceiling hanging, more expensive bag. The wavemaster is made with a heavy vinyl covering.
