I used the bat gage, but didn't like it much. Then I switched to the edge checker. I thought it was OK for a while, but I noticed I would get a different reading when I put it on the opposite side of the skate. I just got a BR100 and this is definitely the one to have. After getting my edges straight with the BR100, I realized the edge checker had always been off. FYI - I tried to order from skateworks since they have an online order page, but they no longer sell it. They sent me on to blademaster.
