I did not find the advantages of the product, I do not recommend it.
I asked the manufacturer's manager what sets this model apart from the GA 5030 before making a purchase.
There was no clear response given to me, and no indication of a full-length button, so I shall try again.
Pros
Those who are skilled with their hands will appreciate that the power is cut off as soon as the key is released.
Cons
The power button is quite inconvenient. There is no key lock and no soft start. The broken key cannot be fixed. I called the service center to inquire about the availability of such push-to-start buttons, and they advised me to place an order with Hong Kong and wait.
