Shopping experience was nice. The constant emails to leave a review are a bit excessive, and then when you do review it you cant just leave it with the stars you select you have to write something. I understand that it's important for customers to read them about potential purchases, but I bought these for my husband and I am not using them. Hard to come up with an honest review, I know he liked it, and I know he used it and it worked but aside from that I don't know much more.
