works well 😎 Good stuff better than all the other **** you see online would recommend i got strongest one 44% gel so dont know about less strong ones but its works great in couple of days 👍 5 stars ⭐️ ⭐️⭐️⭐️⭐️😎😬

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.

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.

Excellent professional grade products! I have been using these teeth whitening products for about 7 years now. Professional grade, easy to use, and amazing results. I do monthly touch ups to keep my smile bright. The pricing is excellent! I recommend getting the the blue mineralizing gel also and use immediately following each treatment. I do not have any sensitivity when I use the two together.

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.
