Ok. My take.
The chock sucks and thats been mentioned above. You can replace it with something better and any upgrade will be a great one. So, you bought a lift and now you need to buy extra chock setups to have it work better. Time and money added.
The drop out for the rear wheel is nice, however its a bit flimsy in that area. You can reinforce it with scrap steel. More time added.
The whole table top, the diamond plate top is flimsy. Sometimes ill chock the front and get the bike on the centerstand and you can see the table divot/flex when the centerstand is.
Tippy. Yes, its tippy. Get a heavy bike on there and get it lifted up and youll move very carefully when youre doing any heavy duty work. Now, i am a tall guy, so i usually like it raised all the way up. Thats my experience with it being tippy.
The hydraulics seems ok though, and the safety bar is a nice touch.
When you load a bike onto it, even with the leveling legs properly lowered, sometimes the front of the lift will wheelie and its annoying and loud when it slams back down.
If I am working on a scooter, ill use the HF lift.
If i am working on a small cc bike ill used HF lift carefully.
Anything bigger than, I dunno, CB 500, Ninja 500, SV650, V7, etc, it goes on the black air powered lifts with the good front wheel clamps. (1500lb?? capacity? maybe 2000lb?)
My two cents. Your results may vary
