I bought two flash heads from Interfit under 2 years ago (Purchased on 10/8/2019). About 2 months ago one of the flash tubes broke and when contacting Interfit to get a replacement I was told that they now no longer support the product and I couldn't get a replacement tube. This light is now totally obsolete and I am very unhappy with Interfit. If when purchasing the flash heads I was not told that they were discontinuing the lights and that I would not be able to get replacement tubes just 20 months later I would never have bought them. To have such a short after sales care policy is ridicules and their customer support was very unhelpful. Very dissatisfied with a purchase which was ultimately a waist of money.
