Hi, welcome to the forum
I am a little surprised that your products have had a a somewhat hostile reception from some quarters
Pesonally, I think that most knowledgable folk would understand that quality engineering cost's a good deal more than a similar product that has been made to a price, basic in construction but functional.
For my own build, the product exceeds my needs, that said, if I were building an out n out track car, I wouldn't flinch at the price.
One thing for sure, I would much prefer to see someone coming on to the scene with a good quality product that is priced accordingly than someone appear, offering a great product at an unrealisticly low price !!??
Just a suggestion, perhaps it would help if you put a location in your profile
A nice bit of engeneering & wish you well
