Prowriststraps bands vs jump stretch bands

[Xplosive]

Hello all, nice board.
I'm looking into the stretch bands for my o'lifting/ powerlifting training. I was wondering, has anybody tried the stretch bands from prowriststraps.com, http://www.prowriststraps.com/bands_powerlifting_weight_lifting_band ?
How do they compared to the original ones from jump stretch?

If they are similar or better I'd rather purchase them from prowriststraps because I've already ordered stuff from them in the past and the service was great.
