Good, but buy extras.
Verified Buyer Reviewed by Florida Prairie Campers from South/Central Florida on Sunday, May 31, 2015
I bought several sets and about 20% of the units didn't work. We just trashed the ones that didn't work and kept the ones that did and matched them into red/white pairs. So it cost a little extra in that way but overall it was a good deal. I wouldn't buy just one set though.
