I told some people I would let them know what I thought after a couple days. My 3 boys are 38 months, 24 months, and 7w. Here's my review thus far:
Fit is great. Super trim and snug, and I don't have to go up a size in pants with any 3 of the boys. With prefolds and covers their pants were tight, but also lumpy and you could see the fold lines. I'm vain, apparently, but I didn't like it!
Absorbancy is good. I have had a couple leaks, but just from them getting saturated. We're still figuring out exactly what works, but 2-3 hours seems to be the changing point. Most of the time this is fine (though a little strange after going 4 hours in disposables), but when we're going out it's helpful to double up the inserts.
Nighttimes.... I've only tried these at night last night and we had no leaks! I doubled up the inserts and wrapped them with a microfiber auto towel I bought at Walmart ($5 for 8 towels). Normally I would use a premium prefold with an infant prefold inside it. HUGE. Laughable huge. We have a giggle party every night when we put on their "big" diapers and they parade around in their gigantic butts! Double-stuffing and wrapping the inserts really didn't make these very bulky at all.
Construction seems great, though I'm new and have no basis for comparison. They are PUL with a soft microfleece liner. The snaps have reinforcement fabric on the underside and seem good quality. I haven't had any problems with the legs gapping, and the elastic on the back pulls in snug.
All in all, I'm thrilled. I have read some reviews online with washing instructions, so currently I'm running a cold cycle, then I fill the tub half full with hot and switch it to warm, with a warm rinse. I only put the inserts into the dryer and line dry the pockets, mostly because I want them to last until LO is PT'ed. The washing instructions say to wash in hot, but the temperature is listed as 104*, which I'm pretty sure is warm. I think hot is more like 140* or something.... Correct me if I'm wrong.
