Thermoelectric Energy Demonstration Kit

I have dealt with this company for many years, and the customer service is great. When I first received this kit, I was shocked at the tiny size of the motor. I asked for a larger motor that would be easier to work with, but was informed the motor was specifically designed for this demo because of the low voltage. The wires are so tiny on the motor that it is very difficult to keep the wires connected to the Peltier device. Any slight movement and there is a loss of connection. My wife did a great job attaching electrical clips to the motor. However, she had a very difficult time stripping the wires. I would include a photo of the modification but can't here. My suggestion to make this kit work better is to solder electrical connectors to all the bare wires. I was disappointed with the 9v battery to the Peltier device, and got better results with a lantern battery. However, I learned that the battery that came with the kit was not a full 9v. When I used a brand new battery I got better results. It is a nice little kit that I think would be way better if all bare wires had electrical connecters. Since I was told the kit is made by this company I think a little extra effort to add electrical connecters would greatly improve the kit. Also, make sure the 9v batteries included is a full 9v.
