I just recevied my
BAL 28050 about a week ago. It is Very Nice. Sturdy, uses a 3/4" wrench and is pretty "easy" to crank (little grease on the screw would help). I was able to slide it under the wheel and raise it a few inches without breaking a sweat (it was close though).
I bought it in an effort to reduce getting in and out, guessing, driving up and down blocks, and also to test my wireless leveler. I liked the BAL so much I bought another one for my friend, which just arrived today, he is excited to try it out. It also is a great wheel block with no wheel rolling. Anyway, I Like it, wish I bought it sooner.
