So far so good. I will have to see the product for the full review.

Everything in stock

Automatic adding paid shipping option and insurance, made it hard to navigate through. Kept changing back. Otherwise, a easy transaction.

excellent price, free shipping as actually stated and still $25 bucks cheaper then other places

easy clear website

GOOD PRICE!

Easy look up easy check out

Very good experience

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.
