I have a couple of them, but I've only used them twice. They did the job fine both times.
They are so inexpensive that I will keep them for backup and/or emergency use or when I have to have two setups in place at the same time.
It happens a couple times a year.
I like the way they sound, and the weight and the price. Also, when one of mine arrived damaged it was quickly replaced with no questions asked.
