This is the RH model which has the controls on the right hand grip on the blower chute instead of separate from the chute on the left-hand side. Much easier to control and gives you a free hand. This one is marked number 1 (because I have two of them) and is about 3 or 4 years old and has plenty of use on it but still runs fine.
