It's very good yes! Not the best for in my garage, as it doesn't have the space to pick up every ball - but it picks up most.
At the range though, it's perfect!
It's fun if you want to blast through a round or two in an hour, on the subscription based "Home Tee Hero".
It's really good for helping you work on keeping your shots straight and receive distance measurements.
When my new clubs arrive, I'll be using it a lot, to get some good averages on each club, using around 100 odd balls per club, if I can.
I've not used it so much in the last couple of weeks though, as I've purchased membership to a nice little 9-hole course and I've been going there on lunch break instead.
On that note, I hit my best score yesterday, of 9 over on 9, (4 pars, 3 bogeys and 2 triple bogeys).
Went out today to try and beat that, started off really strong - had 2 pars, 5 bogeys, then I got to hole #8: my nemesis. Ended up shooting 10 on the narrow par5. Finished up with a bogey on the 9th. If I hadn't ended up behind a tree off my drive, I think I woulda ended up with a 7 over for the 9 - which woulda been by far my best score. Back at it tomorrow, as long as it doesn't rain!
