I've used it for two batches so far. It's worked great and holds temperature well (I place a towel over the cover since the lid isn't insulated). You can do up to 5 lbs. of grain with 1.2 quarts of water/lb. but that is literally the maximum. Works great for doing partial boils though.
Put me down for endorsing the 2G cooler method. I'm terrified of any DIY projects, yet I was able to put this together no problem for about $20. The exact parts list is even posted in the thread. Definitely look into it.
I still do partial boils on my stove, but I'm just very wary of stovetop mashes. It'd seem like effeciency would be very low and sparging would be more of a challenge. Plus the cooler method is a VERY inexpensive way to teach yourself the AG process for whenever you'd be willing to take that next step.
