It was a waste of money. I used the 44% and it didn't do anything to whiten my teeth. I used it exactly as the instructions said. I guess it must be old. There was no taste to it like I expected. I will be purchasing another brand.

I wasn't happy with the result so… I wasn't happy with the result so returned the products. It took long time to get refund and they didn't give me the full refund. I contacted them few times over a month and they told me that they charges a spoilage charge 20%. They charge high shipping fee, the return postage fee has to be paid by customers and they take the spoilage fee from the refund. It's not worth the price for the product and they are not good at responding quickly, very disappointing. I definitely don't recommend to purchase the product especially from oversea.

The product arrived in damaged package The product arrived in damaged package, after several weeks. The gel smells of pure bleach and it has burnt my gums and inside mouth after 1 use, used minimum amount of gel too as quite cautious. Contacted company on several occasions reporting the problem, with no response… Would definitely not recommend at all.

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.

Order has not arrived Ordered in the middle of May and it still hasn’t arrived. I have emailed to asks or information but have received no reply. Was warned deliveries might be late because of the virus but this is worrying.
