Diamond smile UK !

I ordered a hair blow dry brush, which I cancelled 20 minutes after ordering,when my bank flagged the company.
I had checked the company out and they go under Diamond smile UK ! It is in fact a German company.
Even though I cancelled it by email, as there was no telephone number, they still shipped the brush.
It came 12 days later and to return it has cost me £14.25, which I am contesting as they should never have sent it.
Don't use them !!

Refund…

I purchased some gels from this company, but after reading reviews, became very uneasy about using them.
After contacting the company through PayPal, they gave me a refund instantly.
I cannot comment on the efficacy of their product, but cannot fault the refund policy.

Item not received

Ordered over a week ago and apparently shipped same day. Not yet received (Royal Mail tracking still says they are expecting the parcel). When raised, have received nothing back.

This is a scam

This is a scam! Delivery not made, and machine translated emails coming from company claiming they don't have recipient's full address; and that recipient did not pick up delivery. They claim to deliver with DHL in 2-5 days, but claim I did not pick up from "post office". Meanwhile, tracking info says that delivery is "being prepared".

Awful

Awful. Was sold defected teeth whitening that made no difference at all to my teeth. Clearly they are selling Pola Night that has expired as I have never had an issue with this brand, so I plan on reporting this company to Pola Night and trading standards.

Spoke to the same receptionist on two occasions on different days.
Was told by her that I was rude. Have been going there for over 20 years and have never been spoken to like that before.
My dentist is reena and she’s fantastic.

Something is wrong with this product

Something is wrong with this product. After 2 weeks mine teeth got new stains, became yellow. It was a disaster. I stopped use this product, begun pulling with coconut oil and I successfully treat those ny stains.
Now I had paid something that not only does have promised effects but had harmful effects on me.

If you live in Norway you will have to…

If you live in Norway you will have to pay customs and taxes, even though they write that they ship from Norway, which *should* mean you are exempt from that. I wrote them an email asking about it, and they were not very nice about it, saying that I would not get a refund if I didn’t pick up the package. This seems like a scam, with really poor customer service support, don’t order unless you want to pay extra for a product that you don’t know if you will keep or not!

Everything went wrong....

Everything went wrong....
Did not receive that the package was ready for p/u
Sent an email and asked what happened with my order. Got an answer back that it was sent back to them.
Asked for a refund since I was on my way abroad and nobody home to pick it up.
Got a very strict answer back that thats not possible to refund any money.
They can resend it but whats the point when it will be going back again....
I will never use them again.
This is not a good customer service.

Do NOT buy this product, its terrible. Save

You have to read the small text on the site, you have to pay extra taxes! The custom survive s#$ks I wrote to them about an hour after ordering and they said I could'nt because the order was already shipped, I saw on my order update that my order was shipped 2 days after I tok contact. When I mentend taxes they said that they would refund it, NEVER HAPPEND! And the product is terrible! BS company who just want your money and the product is real bad. Do not buy! SCAM COMPANY

I was nervous ordering as i've been ripped off by a company that didn't send the products i'd paid for.
Not the case with My diamond smile they literally came the next day. I got exactly what i'd ordered. 4 syringes of polanight. The price is reasonable and the products aren't fake. I've used this stuff before and know the difference. Thank you My diamond smile for restoring my faith. I shall be using this company again.

More expensive than from the dentist

Ordered 4 x 16% Polanite syringes for £32. When they arrived they were only 1.3g each!!! ie. a total of 5.2g. Considering I could buy 2 x 3g shringes from my dentist for £30, they are expensive even before postage costs. What I am more annoyed about is that the size of the shringes mentioned in my order. Will not be buying any more, other than from my dentist!!

Perfect on price and service!

Ordered on a Friday afternoon and, as promised, it was dispatched the same day so that my gels were delivered to me in London by Saturday morning. Fantastic!..... and the price was great too!
