I think they're great too. In fact, they're so good that I'm also switching to DUI zip seals and will be selling my Ro-Locks too.
If interested, please pm me ...

Yep, I use Ro-Locks and haven't had a complaint from them. I use them in a Pro-tec suit and will be shortly moving over to zip seals on a DUI so I will have a pair up for sale fairly soon
The really good thing is that they are easy to change if you hole them (5 mins maximum).
