Already two orders received. The 24 spots all work for over a month and no problems. I am very satisfied. So much so that I spent my third order I receive usually within 2 days. Note that they illuminate more than indicated by the announcement: roughly equivalent to 50W halogen, that is to say that I had before. In addition it is sold and shipped by Amazon, so if there are any problems (which I doubt) you know you are reimbursed on the nail; and in addition the return is free because the return label is provided to you by Amazon. So a tip: you can buy eyes closed, you will not be disappointed. Besides, for my part, if I need additional spots, I will order a fourth of those 12 spots without hesitation!
