I am enjoying the v900L. I like the weight, much more comfortable to wear for long periods. The battery is great, gives us plenty of time before recharging. The LED light is great, very bright and the polarized position seems to work even better than the v300. I have been using Syris products for about thirteen years and this new unit has definitely evolved, with better light, and longer battery life. Overall, a great indispensable product for sclerotherapy and I also use it in the reverse position when doing facial fillers. When the light is in the non- polarized position, it extenuates the wrinkles making filler placement more accurate. When I do sclerotherapy training, I always recommend they start right, and purchase a Syris head lamp.
