Well I am one satisfied user of the Harbor Freight yellow one. Why...?
1) Price was right (at the time I bought it with discount coupon on sale, it was $54 out the door...more money for your bike.
2), I am a "casual" user that only uses it for times where a lift is NECESSARY and CONVENIENT so I do not use it to move my bike or store or multiple bikes to convert it into a "ROLLER".
3) I use my bike virtually year 'round, I've learned to service bike quickly on the jiffy stand or lean it 'gainst wall/fence with bike hooks and Ancra straps out back, put ol' fashioned wood blocks to steady it underneath and I am off and running, the way I did it before I got the lift. Just my way...:s!
Don't forget to bungy cord the jiffy stand so it does not fold up on you as a precaution, use safety straps to prevent that first "slip" and use a friend as a spotter the first few times you use before doing it solo with that stand.
