    "Great service, great price!"

    "I would recommend them. They have a phone number and answer the phone for an enquiry regarding a prescription. They accept images of prescriptions written from European mainland veterinary clinics. Prices are good, certainly on some of the more expensive medications."

    "Easy to use website and step by step guidance to add the prescription. I made an error on my order and I was contacted within an hour to discuss and correct it. My order arrived the next day and was packed safely.
    Unfortunately and unexpectedly my furbaby passed away on the day of delivery, I contacted them and they agreed to take back the medication and I received confirmation the same next day.
    I spoken with customer services and they were so pleasant and helpful and even gave me their condolences.
    Overall I am extremely impressed.with this company and would highly recommend them to everyone.
    Thank you for everything."

    "The product I order regularly had changed and the system picked up the wrong product so I’ve ended up with a 12k bag of dog food (£52) that I can’t use. Customer services very unhelpful. Will not buy from them again."
