What is the brand/source of your impact bag?

[TheHeat]

I have had an impact bag failure after only two days of use. I am using mostly the dowels, but did use a club a little. Busted the seam right out. While I admit that it was two days of fairly heavy use, I don't think this should have happened this soon and will be returning it. Seems like these things should be designed for abuse.

Just wondering what the top brands are and the best place to get them.

Thanks,
