Yep, we've got a pair that we use regularly. I think the jacket is good, with the little rubber seals around the base of the arm keeping most of the water out. The fleecy bit around the mouth/neck can be susceptible to becoming soaked when not done up stupidly tightly, and then when you do want to tighten it up it becomes very irritating.
They are certainly the strongest part of our kit, the Marinepool sallopettes are nowhere near as good.
One point the seller made when we bought them at the LBS last year was how much more flexible they are than other jackets of a similar price. Those from competitor brands and also Gill ones below it in the range were surprisingly stiff and of course that will only get worse in sea water.
