My opinion......unless you live in the wiilds, don't bother.
We have a practice net at the club, and even with double walling balls still manage to escape.
I wouldnt chance it.
It's fantastic, can put it up or down in 2 mins. Bought a used range mat from my local driving range and it's a great little set up for less than £100.
In my mancave I have a roll of heavy carpet that hangs down and I can go full tilt at it and the ball just drops to floor,out in the garden I hang same roll over clothes line for same effect,cost me 5£!! It's perfect and I'm only working on strike which is all you can really do into any kind of "net" so I'd say get creative and save a few quid, quite a few of them online don't look to sturdy....
