I bought the xB-452 so both hands went with it. I use the longer arm for car and truck tires. Easy to use after watching the video on beedbuster.com. Loved the advice he gives you on tire refitting. I took the tires off my 6 wheeler to paint the wheels. While 8x12 and 10x10. They wanted to withdraw and refund $30 for each tire here. Register 2 days before the start, then I will sandblast and paint the wheels. Two days in advance to wear again and a second trip to the store. I'm tired of driving back and forth to queue at shops. My six wheels, I paid for this tool the day it arrived!
