Don't buy this product- you will not get your whole order. We ordered 2 start packs and paid for them. They shipped one. We have called every week for a month. No shipment. We have sent emails no return. The customer service is the pits and they seem to be ripping people off by not sending whole orders but taking the payment. Oh yeah the battery life stinks. There are better products on the market. DO YOUR HOMEWORK FIRST !!
