I would steer clear and not even try it, knowing that you can return it to Amazon.
I didn't look at the radio you mentioned at all. I just went straight to the reviews. Of note: (1) Every review was on the plus side. (b) Only one review was from a licensed HAM operator. (iii) EVERY REVIEWER RECEIVED THE PRODUCT FOR FREE, IN RETURN FOR THEIR "REVIEW".
But, if you're still looking at it, they have a "9 Watt" GMRS HT.... Again, all reviews are from Amazons Vine Free Product Review incentive.

Good luck. I'm new to all of this radio stuff too. But I'm old in mind and body
