Stop holding a charge after a few months!

I had the clarisonic smart profile before and it worked great. It lasted a couple of years and I decided I wanted something smaller and portable for traveling. I got the mia fit on Sephora's sale. It started off great and did the job perfectly. Until after a few months, I noticed I had to charge it more often. Recently, the device merely hold a charge for 1-2 uses. Highly don't reccomend!

Is it good product?
