My pipet-aid has been performing poorly this week, so I opened it up this morning, just enough to replace the battery. After putting it back together, the thing wouldn’t suck. I’ve now taken this damn thing apart 4 times, examined it, and put it back together. Each time, there was a new problem.
Now I’m stuck with this and completely confused:
This is why I didn’t take things apart as a kid. This is why I’m not an engineer.
