I bought some computer strain glasses off fishpond in Jan this year, and the item broke yesterday. All things considered, my judgement is that based on the price, they should have lasted longer.
That said, I contacted Fishpond, but also made an online query on the suppliers website who are based on the US. They indicated they had a defective batch etc etc and would send a replacement pair.
Interestingly though, they mentioned, they only sell via Amazon and have no contract with Fishpond and I was likely sold a 2nd hand pair. They did not seem used based on the packaging but equally the glasses are not for sale on Fishpond anymore, but are still on Amazon.
What do you think? and how do Fishpond operate?
