Using cheap "hobby" motors in a product?
I have a project, and I'm evaluating making it into a marketable product. Motorized parts are a key functionality. In my prototype, I think I used this SparkFun motor, or similar: https://www.sparkfun.com/hobby-motor-gear.html
That worked well for prototyping. However, this product is not a toy, and it could be expected to see some rough handling occasionally.
I'll throw in that another requirement of the project is that multiple motors need to fit in a pretty small enclosure. Ideally, motors even smaller than the SparkFun one would be preferable.
Does anyone have any thoughts on using a "hobby" motor like that in a product? Experience with durability? Recommendations of where to find the best motor to suit my project's needs?
