Purchased one of their most expensive items at a cost of over £50. It kept falling off. The locking clasp is useless. I have e-mailed the company about this and had no reply. I have phoned on numerous occasions and left messages of their Giffgaff voice mail and not heard back. Customer service is non existent. Do yourself a favour and shop elsewhere. Nice looking product but unfit for purpose as the proxy thing falls off at least 12-15 times a day. Drove me crazy. Previously Had one off e-bay for a tenner which lasted for over 5 years and only came off about once a week.
