Is Kent Turbo Strontium like Purple-up?

[sgreth]

I'm looking to buy Purple-up, but I see that SWF.com doesn't cary it. I'd like to buy a few items from the site to support this BBS. So, my question is: Is this Kent product similar to Purple-Up, and does anyone have any cheers or jeers for the product?
