I purchased 4 things on groupon, and will never buy from them again. The products were all cheaply made, did not work and/or never received. They only have phone assistance Mon-Fir 9-5 then your on hold for at least an hour. Groupon does not respond in an efficient manner by email or handle complaints. I paid for a product in December that in February I still have not received and they suggested giving me Groupon credit as if I would ever purchase from them again or like it is my fault the merchandise was not mailed as required.
