You pretty much got it in 1 there Gel. Just one additional pet peeve of mine: if you order a small percentage of grey hair, you want the grey hair to have the same texture as the colored hair. I have had a couple of units (not from Toplace) where the grey hair was far coarser and seemed to have a different curl from the rest of the hair, and from my real hair - total giveaway that it might be a piece.
