Service Rating: szybka dostawa, dobrze zapakowany towar, ogólnie dobra informacja o produktach na stronie.
Product: nie daje skutków ubocznych, kapsułki niezbyt duże, dają się łatwo połykać, ogólnie samopoczucie mam dobre, ale za krótko używam, żeby konkretnie coś powiedzieć
Service Rating: 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.
Product: I feel that my circulation has improved in my legs, but I think I need a little longer to give a full evaluation. In my experience it is best not to give a final rating until one has been taking that particular supplement for an extended period.

I'm 83, and many websites tend to pester and advertise afterwards. I'm not used to that. I went to you for Lutein in the first instance, and have decided to stay with you as long as you continue to be helpful but not pushy. (John)

Service Rating: Easy to navigate through their web page and super quick delivery.

Product: Brilliant, as described on the web site.
Pills all opened up and emptied the contents
Feedback Response: We were sorry to hear that some of the capsules had opened, but as soon as we were advised of this, we rushed replacements out to you, plus we refunded you in full for the affected product. Unfortunately - for all retailers - there will be occasional issues with even the best quality products, but for us, a measure of good service is how one responds to these issues. I hope you will reconsider your 1-star service rating, as it's difficult to see how we could have responded in a more timely or effective manner.
Hasslefree & quick delivery.
Good packaging, post flap friendly.
Service Rating: Excellent
Product: I have tried quite a few other suppliers but I have found Just Vitamins to be the best.
Please stop pestering me .
