This is a great L - screen. It works very well.
HOWEVER, the wheels sometimes lock up and stop spinning, there is a small separation where the left side and right side meet - big enough for a baseball to go through - but its not a big deal. I don't know about you, but i do not like the the curved corners. The ORIGINAL price does seem expensive, but get it on sale and you are set.
On the other hand - the good hand - it is very easy to assemble. It took me about 25 minutes to put it together all by myself. The wheels make it much easier to transport, especially outside. I got it on sale, and it is so worth the $115 that I spent. the wide base keeps it from tipping. It comes with Velcro straps that hold the net to the frame - very cool.
All in all, I strongly suggest this product - as long as it is on sale, which is almost all the time.
