I really wish l had checked reviews before l bought 3 units. Its a scam of a company, the products arrived but no name on them and just states made in China. I didnt bother even requesting a refund, l went straight to my credit card company and told them it was a scam and l was refunded. After the credit card company contacted them, they asked me to return the products but l would beed to cover the initial delivery costs and return costs to Hong Kong. No thanks!
