I've got two Linea cases - a four wheel spinner carry on, and a two wheeler that fits a suit (wrap around style)
I've used the four wheel spinner almost every week for the last two and half years - sometimes it's just being dragged the mile from my office to the hotel, other times it's doing transatlantic flights
It has plenty of pockets which I like, and overall it's lasted pretty well, the pull up handle is starting to get a bit wobbly, and I'd prefer it to have two wheels rather than four but for the £60 (in the sale) I spent on it I'm very happy.
The suit carrier I use less often, it's a bit smaller, fitting a suit in it is a pain, and the zip jams sometimes (I think it was £40 in a sale)
Construction wise the nylon on both is pretty thick so should cope with baggage handlers - we had some lightweight cases that we took to Australia, and the nylon got torn on something during transit.
My overall view is they're pretty good value for money, you can look at them in the shop and they buy online.
I've considered buying some Briggs and Riley cases but ultimately didn't see the benefit of spending 5x more.
