Bought two. After a short period of use over the next two to three weeks, one of them broke. The yellow pad is deformed and does not stick to the clips. I do not recommend it to anyone. Also, it took 12 days for customer service to respond to my email. They then said it would take them about eight weeks to decide whether or not to replace the faulty tool. I personally would not want to buy this model again. I think it's trouble.
