Rounding up from 4.5.
I have very light skin. There is dark hair on my lower legs, underarms and bikini area. These areas grow fast. I had a 5 o'clock shadow and needed to shave those areas every day, sometimes twice, in the summer or on tropical vacations. My facial hair and upper legs are blonde. I could never tolerate wax on my face due to breakouts. Threading face and neck was my go to for the past 10 years. Then that started breaking me out too, no matter how I prepped or treated afterwards. I researched pulsed light devices, but decided on diode laser because it treats lighter colored hair better than other devices.
I started using my DermRays V4S 9 weeks ago. I started at 3 x a week and continued that for 5 weeks (was on vacation the 4th week and didn’t use. Also, only needed to shave every other day!) After 5 weeks, my hair growth was slower and sparser on my legs and face. Underarms and bikini area, I only noticed a slight decrease in hair growth time, but still full area growth. Dropped to 2 x times a week, as instructed. At 9 weeks, I am noticing slower and sparser growth in the underarms and bikini area, but it is taking much longer to see results there. It has now been 3 weeks since I shaved or lasered my face. I will do that this week. Since I can only treat my lower face, I was pleasantly surprised I don’t miss treating my forehead. My upper legs only need treating once a week now. I also only need to shave the areas right before I treat them. So far my V4S is saving me a lot of shave time. However, it takes a solid 40-45 minutes to treat my entire body. I break it up into sections over 2 days, so I don’t have to spend all that time at once. I have been using the highest setting everywhere since the second treatment. Only on occasion, if I sweat a bit, I will feel a slight zinging while treating the bikini area. Otherwise, no sensation. The cooling system is a must. I will continue treating lower legs, underarms and bikini area 2 x a week until those areas respond like the others. They are very clear this device relies on the pigment of your hair. But it does work on blonde hair. This is a huge difference for me between this device and the pulsed light options. Well worth the cost.
Pros: Treats blonde hair (not white, grey or red). Cooling system makes treatment pain free. Easy to use. No glasses required. Multiple safety features. Multiple treatment strength options. They are honest up front on who will benefit. No limit on pulses. Can treat the same day as shaving. Has not irritated my sensitive skin following the instructions, especially about facial cleansers, retinol and sun. Works well when following the instructions.
Cons: Hair free takes time and consistency, months. This is a significant time investment. The unit is heavy. I had to wait to use it until I completely recovered from rotator cuff surgery. Doesn’t work on white, grey or red hair or very dark skin tones. Expensive. Relies on the contrast between hair and skin tone over which we have no control. Takes a full 45 minutes to treat face, neck, underarms, bikini area, top of feet (I'm part Hobbit), and legs. Must be consistent. May take longer to see results on underarms and bikini areas.
Highly recommend 4.5/5.

I purchased this at Christmas time when there was a good sale. I had already been going to a salon to get laser treatments, and the salon is using a diode machine as well, but being able to do this on my own every other day has been a game changer. While the hair is still coming in, slow and soft, I can now go at least two to three days without having to shave. I am hoping if I continue with this schedule, that I will see hair "gone" for longer periods, especially bikini area during the summer!
Straightforward and effective for my busy morning schedule. Staying patient with the process has paid off and my skin feels great. High quality build for the price.
I'm a college student so budget matters to me. This is affordable yet effective. It takes some patience but the results are worth it. Pretty straightforward for someone new to at-home laser treatments.
