Before seeing these pictures this morning, I tried something very similar to this last night. I cut about a 5 inch piece of tape and placed the midpoint of the tape across the top of my finger, just a little outside the unit, then wrapped each end around and down to the bottom of the unit where I attached the ends in a criss-cross or X pattern. Even doing this though, I managed to slip out of the unit once last night as I guess if you bend the finger, the top part can still open slightly allowing your finger to come out. I think I'll try your method tonight. Instead of draping just across the top of the finger, I see you also manage to catch the top edge of the CMS-50D+ just outside of the menu function button under the tape, so that should make it pretty much impossible for your finger to slip out. Appreciate the pictures! Do you tape with fairly light pressure on the top of the unit? I have noticed like Paula says that if you put too much pressure on the top on the outside end, the hinge does flex on the opposite end and you can get some faulty readings. Only one thing...isn't it kind of hard to type with that thing on your finger???
