I wear both the 7mm and 5mm versions of the Stingray. The 7mm has around 100 dives and is holding up extremely well so if you asked me, I'd say go for it! The 5mm has made about 25 dives and did great. It's essentially the same suit, just thinner.
But, to be real. The pros:
1. Front zip
2. Very warm - my usual dive temps range from low to high 50s and it's fantastic.
3. Padding on the lower back
4. Semi-dry and while I'm not completely dry, I'm not soaking wet, either
5. Excellent durability
6. Great value for the price
7. Easy to put on. I can get this suit on in record time with no struggling.
The cons:
1. It's a semi-dry so water will well up around your ankles. (if you pee in your suit, it's not flushing out!)
2. Zippers on legs and arms. You need to make sure you keep them clean and free of debris. Most suits don't have five zippers and while I don't care, it's something to watch.
3. NASCAR marking. I think they went a tad bit overboard on the CAMARO STINGRAY stenciling.
Hope that helps. I get a lot of compliments on it when I wear it and I plan on using these suits for years and years to come. They are fantastic!
