Great when wet! Little tabs break off! - We use this for Build a Boat kits. Many of our boats tip and submerge but the motors still work great. So that's a good thing. The problem with these is the little copper tabs are too flimsy and break easily. We use 40 motors for two weeks and we lose probably 10 (25%) of the motors because of broken tabs. That seems too many.

Neccessary for the Catch the Bug Project - This is my 3rd year running the Catch the Bug project and lab in my Technology and Engineering 8th grade course. Unfortunately the students tend to break the leads to the motors in the kits so getting this back up motor pack is necessary to this project.
