i only used 3 of them and it really works! the result is so obvious i am very excited!

This stuff works really well. Very happy with the progress.

Great quality whitening gel with trays, recommended by dentist. Really White's, second time purchased.

It does a good job of whitening, it's noticeable after a few sessions. My only issue is the inner tray often stays stuck in the outer tray. I bite down the way the instructions say, but when I remove the outer tray I often find the inner tray is still inside and then it's a mess to try and get it in place.

Does the job

I think the prefilled tray works best on teeth that are straight. Whitens the hell out of them if you leave it on a little longer than recommended. Don’t go nuts with it though because it will bleach your gums.

Have not seen much of a difference so far but only used three times. However, my teeth are sore already. There is too much gel and overruns onto my gums so my gums are very sore and some sections white. Have to take a break.

My dentist office wanted $190 for these!!!! Most other in offices charge the same, unbelievable! This is the best price around. They also work better than any other whitener on the market (i think). You can notice a slight difference after just one use!
