Finally time to change the batteries on the Speedstir! I’ve been dreading this day lol. Going back to manually testing SUCKS! Anyways, I cannot find a screwdriver small enough to unscrew the bottom and change the batteries. WTH was Taylor thinking? Talk about making things as annoying as possible lol. Anyways, is there anything else I can use to open the back or the name of the specific screwdriver needed? I’m not very handy, obviously lol
