I bought this whitening kit for the bluelight! I was super excited to see if it'd make a difference as opposed to just the strips. the strips seem great. The light didn't immediately turn on and when it did it literally never turned off till about 2,3 days later after exhausting itself. So unfortunately I got one use with the bluelight. it's a bummer I was hoping to have been able to get more than one use with it.

The light really helps the whitening process--however I am taking off stars because it is not reusable! So wasteful and expensive! I was disappointed when I found I could not replace the batteries and just buy more strips!
