HI,
I have one and have about 100 dives on it so far this year. So far, the only thing bad I can say is that the "self-entry" might more aptly apply to a cirque de soleil employee than the average person. Actually, once you get the hang of it, the last couple of inches are pretty easy and you will love how easy it is to zip up. I bought the full meal deal and sizing is pretty accurate. Best to give your LDS your measurements and go from there. I found the zip-up lining to be very comfortable but my zipper went on the 10th dive. I just took it to a seamstress and they put a new zipper in it. Less hassle than sending the stuff back via the LDS. Make sure you get the 3mm socks as they are warmer than using woolies. Also, make sure you get the EVO 3 boots as they are the best ones. I tried the Alterra boots and they were like wearing slippers. I went in and bought the EVO 3 boots and love them. You will get a pocket on the dry suit which is super handy for anything from a pocket mask to a lift bag. Also, remember to get something called "seal saver" from your LDS and use it religiously on every dive. It is kind of a silicone liquid that I just rub inside my wrist seals before I put the suit on. Makes it easier to get on and makes your latex seals last longer. A fellow diver showed me another neat trick in removing your wrists from the seals and sleeves and that is carrying a little bottle of baby shampoo and rubbing a bit on your wrists before you slide your hands out. Less wear and tear on the seals.
The suit is very flexible and the underwear/fleece insulating stuff is quite warm. It was 48-50 on the last dive and 45 minutes was fine. I really like how fast the suit drys out also. The suspension (suspenders) in side the suit is a neat touch. Keeps the suit up where it is supposed to be. Remember to cross the suspenders over your head rather than just pulling them on your shoulders to keep them from sliding off.
All in all, a great suit and about 50% of the people I dive with use the same suit. It even comes with a nifty carrying bag that holds your boots and wetsuit hood and gloves. Good luck. You won't be dissapointed.
