Ordered a teeth whitening kits thinking it would be a good idea to have some "custom trays" that mold to your teeth. That's a joke, they are like mouth guards you used when playing sports in high school and do not work as described. As the other reviews stated, Smilox makes it very difficult to get in touch. Their 800 number only allows you to leave a message and if you submit a complaint via their website, they do not take any measure to touch base with you. I should have read these reviews prior to ordering to better understand the type of company they are. After reading these reviews and not receiving any response to my phone call or email, I decided to call my credit card company and start a dispute process with the amount charged. Interestingly enough, the credit card has a different phone number for them which appears on the statement. With the credit card company on the line, I tried to call that number and it states can't leave a message and hangs up on you. Once the credit company started the dispute process, a company has 15 days to respond. Imagine my surprise when a day later my credit card was refunded... no notice or contact, just my refund; which is fine with me since that is the resolution I was looking for. Interesting that once "their funds" are put on hold, they can immediately remedy the situation. Will not purchase from this company again.
