Disaster

It's not working properly. It works for 1-2 hour after replacing battery and then start blinking green .I replaced it's battery for three times.And Amazon's employee told me that he will process it's return and I should wait till 2nd October for seller's reply.And when I visited the site on 2nd October they didn't processed return.I purchased it with my own money which I earned with lot of struggle and hard workAnd you all Amazon's employees are fooling us.I am very disappoint 😭I only use it for one hour in one day.

Failed when needed

I bought this for an inhouse event, and most important day. I tested everything before packed it and kept it for use on the day needed. But on the day it failed to work. It did not sync any more how hard i tried. Such a waste of money and time.
