I've had the Lifetime Big Adventure playset for almost 4 years.  On moving the unit some of the hardware stripped the heads during disassembly.  Customer service responded to an email requesting replacement parts without hesitation and without cost to me.  It was nice to be surprised by how easy they made it to get my set back together and functioning after a move.  The set itself has been outstanding for my kid and stands out when compared to other standard wooden sets.  Great product, great service hands down!
