The delivery time wasn't too bad… The delivery time wasn't too bad considering it comes from America. However, I've been using the system with the gels bought first (didn't know tray wasn't included so ordered tray separately!) For 2 weeks and not seen much difference unfortunately and that's with the 35%. I also keep reading that these led lights are a gimmick and wont actually help teeth whiten. Apparently it's got to be UV lights that work.

Very dissatisfied Very dissatisfied, I ordered the 35%but was burning my gums and leaving them with white marks on. There is no doubt it will whiten your teeth, if you can’t stand the pain and put up with sore gums. I did not overfill the trays, but difficult due to the size of the siringe. I won’t be purchasing this anymore !

Item never arrived If I could leave 0 I would, I ordered the item a day after a colleague at work ordered theirs. They received their order over 2 weeks ago, I'm still waiting.....so as I haven't received it I am unable to leave a review of how good it is.
