This item was perfect

With every penny!

I used this product the day before yesterday in my upper whitening tray. I used up the last of the 35% whitening gel I already had in the bottom tray. The bottom try worked liked usual - I could see it foaming a bit on the teeth because my whitening trays are transparent. My bottom teeth were noticeably whiter after 30 minutes, like usual. For the upper teeth with this new gel - no foaming at all, zero whitening, but oddly my upper teeth have been a little numb for almost 2 days now.I have no idea what is in these syringes! It's possible they haven't been stored properly - excess heat or simply expired and have entirely lost their strength. I bought this product only because I'm familiar with the names Dentech and Brite White and regret the purchase. Back to the drawing board. Thank you Amazon for the easy return/refund!!

Comes out in a blob on my tray and I use a toothpick to spread it. The black rubber part of the plunger starts coming apart and gets in the bleach itself.

Works great.
