Query: Cannot remove batteries

The compartment on this unit is poorly designed. Once you insert batteries it is impossible to remove them unless you use a knife or thin flat-head screw driver.Get theWAHL 9962-717 Compact Travel Trimmer. It takes a single battery instad of 3, battery compartment is well designed, and it actually cuts noticeably better than this big clunky unit.
