Review (3/5): You do have the change the batteries frequently if you want it to have good "juice" to do it's job
So, I purchased this one year ago. For the price, it's okay. It did exactly what it was suppose to do BUT it died after one year of use. And I didn't use it every day, or even every month for that matter.
When I first purchased it, I had to use it every day for the first month to get my heels looking how they should. Then after that, it was just sporadic maintenance. Once a month or once every other month to maintain. You do have the change the batteries frequently if you want it to have good "juice" to do it's job.
I'm sad it died after only one year. I never had to replace the rollers that came with it though.
Oh well, I'll be searching for a new one to replace it this week. Won't be buying this one again though.
