i have had wraps, roll finger guards and a pair of last years jk neg cut smu split on me. this along with the thumb's on their 8.5 gloves being way too big put me off of sells to be honest. you cannot fault the grip one tiny bit, which is easily amongst the best out there (be it ss, aqua or super4) but i have long had quality issues with them. old ad plus gloves split on me, and i had latex die on to pairs of the old wrap after only a few games.
they also (so far) have been incapaple of getting thier flat palm sizing anywhere near right (they are always at least a half size too big) the 2006/2007 comfort neg cut (supposedly a tight fitting glove) was too big also . the guard sizing was very odd too. the duo flat was perfect , the flat was around 1/2 small and the roll finger was at least one size (probably 1 & 1/2 sizes) too small . i do not see how that can happen . i know you can buy smaller sizes, but it makes it difficult when buying over the internet.
The likes of Puma & Reuschhave got it spot on. i can order an 8.5 in any of their gloves and they all fit perfectly
I will round this off by saying that i may well be being unreasonable (andi appologise if i am), but from a top end (especially price wise) company, i would expect top end quality. My D-Flekt's grip easily as well as the sells SS in all weathers and are as good, if not better in terms of fit and build quality (they are also at least £10 cheaper than the equivalent Sells model)
