I really enjoy the product and appreciate all the effort your team has put into creating it. I have noticed a few things that could be improved to make the experience even better:
1. The battery mode seems to run at only one speed, which is quite slow. The speed controller doesn't appear to change anything when in battery mode, so it would be great if there were more options to adjust the speed when operating on batteries.
2. The batteries tend to press against the contacts and loosen, which can cause inconsistent contact. This means you might need to gently press the batteries to keep them connecting properly. It would be helpful if the contacts were more secure to prevent this issue, especially when using the device on battery power.
3. Using the USB-C connection provides the best performance, but the potentiometer that controls speed only offers a few preset settings rather than a smooth, gradual adjustment. It switches between slow, medium, and fast rather than allowing for finer control.
Overall, I love the product and am happy with it, just wanted to share these small suggestions to improve the battery experience. Thank you for your dedication!
A great gift for anyone who appreciates engineering or science. Working our way through over a hundred Matchbox and Hot Wheels cars; it’s fascinating to see how the *actual* aerodynamics compare with what you’d expect. Highly recommended!
