Service Rating: Items arrived quickly with clear information
Product: I have bought and used collagen supplements for a couple of years. These are well packaged with very clear information and don't need to be taken with food which I find helpful. Not too big although you do have to take 3 a day. So far very pleased and happy with results.

The cost of the products purchased was considered most reasonable and although I live in Spain I received the parcel within eight days.

I am not over keen of the sealed packets and would prefer a container with a better seal.

Service Rating: Received in good time and I like the minimalist packaging but which also details everything about the contents and the dosage, which is not the case with many providers! Also like the clear base to your pack which allows inspection.
Freephone also much appreciated, so no hidden costs.
