Pros: Good value, Good quality, Comfortable, Lightweight, Looks great
Cons: tough to fit
Upgraded from stock generic pinch-bolt cranks and the difference was remarkable, zero flex and no problems with pinch-bolts loosening and the unending creaking you get with them. Feel really solid, look awesome (I got the Matte Black finish) and are lighter than most Aluminium cranks. Only issue I had was getting them on tight, needed to use a couple of rubber mallets, a load of grease and plenty of manpower were required to get them on properly, but you soon realise that once on, they're not going to go anywhere in a hurry. Superb cranks, if you have the budget, get them as they'll no doubt be the lest set you'll ever need. Well worth the investment. Bear in mind the 22mm spindle size, as you may need to upgrade your bottom bracket if, like me, you're upgrading from 19mm. I went with the BSD Superlight Spanish BB, which is also superb.
