EASY TO ORDER

Very easy process

Easy but we'll see how it goes

If you could give a much better tracking information, I'd give 5 stars. You're tracking only stated my order was placed, and received. I had a heavy order. My help was not going to be around more than a week. So I was nervous as heck! The stress of the unknown gave me a headache and made me feel I needed to cancel the order and get one locally that week. But after a lot of praying God came through and I was so happy to receive it on Tuesday after only 4 business days. It was a great price. It seems to work okay on the first day, and I hope it lasts a while. Thank you!

Good price
