Okay, this is a completely honest review.
My son has had nothing but cloth (minus the first few days of the black poop, my MIL said the black poop stained her cloth diapers, so we used disposables) , and we have had the same (exact same ones as you are looking to buy) diapers since then, now at 8 months old. Now, they WERE good, and I'd imagine they'd be good IF you handwashed. The outside of it is supposed to be waterproof, well it's not the material on the outside that makes it waterproof, it's a lining on the inside of it, and that tears REALLY easily, it took about a month for every last one of mine to tear. So we had to get some plastic pants to go on the outside of them, as well. (If you still want to go that route, the Gerber PEVA plastic pants are THE best)
That being said, that is WAY too expensive for those. Babyland and BabyCity and the brandless one you're looking at are all the same, and I averaged out around $1.50 for each diaper, with one insert.
Also, on the subject of inserts, I don't care what kind of pocket diaper you get, you are going to need more than one insert (especially the thin ones that come with the diapers) after the baby is about 4 months old. Make sure the dimensions are right, and get the 3-layer microfiber inserts, they average about $1/ea, and are SO worth it.
ALSO; we DO have to use disposables with my son at night, pull-ups actually (he pees A LOT) , they just absorb more (unless you were to put about 3 or 4 inserts in the diaper, or you got a better quality diaper).
Also; you might not like to, but if you rinse them with vinegar, it A) disinfects them and B) keeps the fleece SUPER soft. It smells horrid when your kid pees (don't do the sniff test with cloth diapers rinsed in vinegar, trust me) but it's a LOT softer and results in less diaper rash with mine
ALL IN ALL;
I will definitely be cloth diapering my next (it's SO simple, SO easy, I couldn't imagine wasting my money on disposables for day-time EVER again) , BUT, I, myself, won't be going with that brand.
If I were in your shoes, I would get a better brand, and don't go with velcro, it's not worth it. Snap diapers are the way to go. Try Bumgenius, pretty much whatever "big brands" are out there are probably good.
It actually evens out, with price, between the cheap diapers and having to go with plastic pants as well, because you have to keep getting bigger sizes of plastic pants as they get bigger, with the one size diaper.
If you have ANY questions, feel free to ask!!
EDIT; Also; I got 48 diapers. It really depends on how often you wash. If you wash daily, probably 24 or so (they go through a LOT in the first few months) but at my mum's house we washed every other day and it literally worked out perfect. As for plastic pants if you're going that route...I would say at LEAST 15 pairs. At least.
Edit EDIT (god I should read through everything before I respond, eh? lol) ; My son was 8 lb when he was born, but dropped down to below 7 lb (long story, lol) and the "one size" snap ones still fit. They have the two snap-holes on the side of one of the tabs so you can wrap it all the way around. Unless you have a teeny weeny baby, the snap ones will probably work.
AS FOR ME, I wouldn't go with prefold, because they're much more of a pain that disposables. I tried them once and they just weren't for me. The snap ones are SO easy. (Also, the 3 layers of snaps down the front are for length adjustment, which is great, but if you're having a boy, watch out for peeing out the top, lol)
