Massimo recently updated their customer support. I know some of us have had less than Stellar response from Massimo in the past but it looks like they've made a major upgrade and taking a big step forward. I entered a a case on their website you can open a case under your account with a broken part under warranty and was skeptical but I got a call back the next day and the tech had me send a picture of the broken part and they shipped out a new part under warranty same-day
Absolutely stay away from Chinese junk, even the ones made in Texas, still junk.
I think an EV from Polaris or any name company would be perfect for her.
good luck!
