I've had this mask for about 2 months now and I've been using it about 4-5 times per week. Overall I'm happy with the results so far aside from some issues with the fit. Pros:-The mask feels sturdy and like its made of high quality materials-The battery life lasts a good amount of uses before it needs to be recharged-The battery recharges relatively quickly -I feel an immediate smoothness on my skin after using the mask-I see a difference in brightness and smoothness on my skin after two months of use-I see a noticeable difference in softening some of the horizontal wrinkles that are forming on my forehead-It's comfortable to wear apart from the fit issues I discuss belowCons:Unfortunately, the fit. It's hard because everyone has a different face shape so I understand how it would be hard to accommodate but from what I understand about red light therapy, the mask works better if it sits directly on the skin being treated. I have trouble achieving this:-While the mask is somewhat flexible, it's too flat so it sticks away from my face in at least one area no matter how I position it on my face. I can either attach the velcro directly in the center back of my head for the mask to sit on the center part of my face and line my eyes with the eye holes but then the top and bottom of the mask sit pretty far away from my chin and forehead. Or I can angle the strap to attach closer to the bottom of my head to hit my forehead or angle the strap to attach at the top of my head to sit on the bottom half of my face but then the opposite section of the mask is sticking out far away from my face. I've alternated how I sit the mask on my face to try to hit all areas during the week, or I try to hold my hand on my face over the mask to try to press it against my skin more in the areas that are being missed. Unfortunately there's no comfortable way to feel like I'm covering everywhere at once. The mask is quite tall for my face so when it is lined up with the bottom half of my face, the eye holes are too high and uncomfortable. Perhaps a few different height options could be offered in the future to accommodate different face shapes and heights. -The way the strap is constructed doesn't help the fit issues- there's one strap that meets in the middle, but it is slotted through both the top and bottom of the mask. Instead of one strap, having a separate top and a bottom strap would help make the mask more adjustable and keep it closer to the bottom and top of the face at the same time (or just making the mask less flat and more curved the way our skulls are so it sits closer to the face). Additionally, the velcro is only on a small part of the strap and if I completely connect the velcro as intended, it is not tight enough to sit on my face closely. I have to pull it tighter and use the very edge of the velcro to get it to fit my face, and ideally I'd be able to pull it even tighter but I can't since the velcro ends. I don't think I have a very small face or head so I imagine it would be even harder for someone more petite.One last small thing is that I'd like flaps with lights for the side of the nose too. I think the one flap on the top of the nose is effective for that area as I see a difference in the smoothness and how my pores look but the sides get completely missed. Overall I like the product and will continue to use it, but it would go from good to absolutely fantastic if it fit better or if it was made more adjustable so it would be more efficient by hitting all areas of the face during each use. For a high price point I'm really happy with the results but wish it was a better user experience and I think it could be done with relatively minor changes to the design.
