"If you're a fan of the considered design and make of Master-piece's bag and accessories you'll love this carry-on. Right off the bat you'll notice the thing is light, so go ahead and stuff this without the additional weight of the trolley. The polycarbonate mixed resin outer is vertically ribbed and shock and heat resistant as well as flame retardant. The casters glide smooth in in all directions to the double wheels and the caster stoppers keep the whole thing in place when your voyage calls for an extended pause. As with all their pieces, storage and neat features abound, one of which being the built in TSA lock, that easily lets you set your code and securely lock your items. At the time of writing this I've done one trip with this but I can personally say I'm quite happy with it and look forward to plenty more years of adventures with it."---Kenshawn
