Full wetsuit

So I've been looking to buy a full wetsuit for Ab diving and found a 7mm hooded suit on Ebay for a decent price.
It's a H2Odessey brand. Anyone have any experience with those? Should I run fast and far from it?

My advise is you should try it on before purchase it.  A wetsuit has to fit a person nicely to keep you warm.  Too tight you'll be uncomfortable, and too loose the water will get in and you will get chilled.

Hi Divers:

        Make sure that that Hood not too tight around your Neck and, check the distance from your Crotch to the Top of your Head.
        I usually buy a detached Hood if it's a Boxed Suit.
