I looked at several different brands of motorcycle lift jacks. The safety catch arms on most other brands appeared to have flimsy looking flat bars that barely catch the safety detents whereas Redline's jack uses square tubing. This is a great jack that is made of quality parts, easy to assemble, and works great. Paired with Redline's SD1K ATV Motorcycle Engine Cradle Dolly allows me to quickly and easily jack up my Road Glide and put it on something solid for longer term use with the ease of rolling around. I highly recommend this product and I would also recommend buying this as a package deal with the Engine Cradle Dolly. Tried using a scissor jack for a while but should have bought this from the start and saved myself the headaches and hassles! [From Redline: Dear Gary, are you interested in a salesman position here at Redline? LOL]
