Pros: Small. Inexpensive. Durable.
Cons: Small. Tee holder didn't last very long.
I bought this little mat to keep from tearing up the backyard.
I was a little concerned about durability as the hitting area is so small that the abuse will be very concentrated without any way to spread it around a bit, but I've had it for several months now and the simulated turf seems to be good as new. The "turf" interaction isn't very realistic feeling but that's to be expected on such a small unit and I can tell a fat shot from a good one anyway. Due to the small footprint this mat doesn't protect the yard as well as I would have liked, but it's better than nothing and the crushed lawn under the mat after a practice session springs back pretty quickly as long as I take care to move it around to a new spot every session. There is a convenient hole on one end so you can spike it down with big nail or something, which I highly recommend, so it doesn't fly into the side of your house and put a big hole in your siding on the first swing.
The little white tee holder broke on the first day, it's still useable but it keeps falling out of the bottom of the mat. This probably wouldn't happen if you place the mat on flat, hard surface like your driveway or a patio paver but if you place it on grass it will inevitable pop out. In any case, you don't really need a mat if you're hitting driver off a tee.
Overall, if you're looking for something small and relatively inexpensive this works pretty well and is surprisingly durable. I think the price point of $35 is a tad high, it would be a much better value at around $25.
