I remain dubious about the lifetime announced 1500 flashes. I did not count them but I am sure that the first one I used for one session of full legs waxing + normal jersey does not facts since it laché before I finished the 1st meeting . I will be more vigilant next time and will not hesitate to make it known to the supplier if needed. plus bulb being still a little over 20 euros it is expensive if it does not take 1,500 promised flashes. but we have no choice we must for this bulb IPL6000 Remington. attention to the replenishment period .. 1-2 months of waiting .. announced in February 2014 but it is perhaps unusual.
