Broke after 6 months of light use

I used this tool in my office for about 6 months. I used it on average 7 times a day, 4 days a week and then it stopped working in the middle of treating a patient. I noticed the imprinted word "adjusting" on the side is spelled incorrectly. There is a hand written "serial" number on the handle. The seller would not replace it and suggested I get it fixed and then send him the bill to reimburse me. I told him no and wanted a 50 percent refund since it did serve its purpose for 6 months and I was offered a 25 percent refund. I wouldn't recommend this product or doing business with this seller. When it worked, it worked fine.
