Didn’t whiten my teeth.

I never received the trays or 1/2 the order that Kim advertised, but paid the price asked.

Used 5 syringes & 1 pen! Didn't work for me at all! Teeth still yellow! All I got where sensitive teeth! On top of that had placed order of 6 syringes and only got mailed 1 syringe. I called It in they didn't believe me! I sent it back took pictures sent them over! I got my refund since original package was still sealed but it was just not a good experience over all! Save ur money it doesn't work!

They're really difficult to put on and keep on
