Reviewing: 3 in 1 Diamond Machine Facial Care Device Equipment w/Vacuum & Spray (Suction Power: 0-65cmHg)I only learned about microdermabrasion after coming across this product, I didn't even know something like this existed. So this is my first exposure, my experience and expectations will likely be much different from someone with more familiarity.My initial impression after first seeing this was intimidating since it's not a typical skin device I've ever seen, and nothing about it looks like it's for skincare. There's lots of parts and bits, and not the most helpful instructions. I suggest extra research into how to use, the instructions mainly explain how to ready the diamond tip, wand, etc. for use. It comes with a spray bottle for toner after you've finished, I've yet to use it though so I don't know how well it sprays or if it's messy. I do wish it came with some sort of brush scrubber to clean the diamond tips and tubing.The instructions don't explain how to use the product, how long, skin prep, what the clear acrylic tubes and sizes are for, or how to clean the tips and tubing. If you're a beginner who feels comfortable with more details, this may not be the product to start with.I've only used it a handful of times, using the smallest diamond bit for about 5-10 minutes on my face with minimum or slightly higher pressure. I first tested on my hands prior to my face, and haven't had any issues so far. It's not unpleasant or uncomfortable and with the settings I use, I hardly feel the diamond tip on my face. I use it twice a week in the morning before my skincare routine, and really like how it makes my skin feel afterwards.I haven't used it nearly long enough to notice any results, and regardless if I did, I'll likely keep using it in my skincare routine - however probably change to monthly instead of twice a week. The process feels very cleansing. The size and shape are a bit awkward though, and it's not easy to store. I've unscrewed the plastic holder since I never use it, and makes it easier to fit places. For replacement parts, I haven't seen any listings as of yet from this seller.For the value (at time of writing), I think it's a fair price. However, I'm very inexperienced and unfamiliar with products like this.
