Query: A poor swing training aid

I bought one of these units from the local Target store. It doesn't give very good feedback on the golf swing as it advertises. The plastic stakes that come with the unit do a poor job of anchoring it during use, and it tends to come loose, which is annoying -- I've tried placing bricks on the base, which doesn't work much better. This is one of the many golf swing trainers that don't do much good, and after using it a few times, it ends up in the garage or the basement with all the other unused junk. I say that your money would be better spent on a few buckets of golf balls at the range to improve your golf swing.
