As mentioned in other reviews, it takes an exceptionally long time for them to fulfill an order. Nothing had happened on my order for 8 days, and when I followed up with them, they indicated the item I ordered was out of stock. I requested a substitution, but even 10 days after that my kit hasn't arrived.
Be sure you have at least 3 weeks after you order the kit before you plan to use it. I had to order a kit elsewhere at the last minute.
