How to choose the best laser

I am recently searching on hair removal laser machines and I can’t find proper information or reviews on so many different options. I am dark skinned, and have black hair. I cut it down to Motus Ax, Gentlelease Max Pro (2021) and Duetto MT Evo (2023). I would appreciate so much an honest review as this is important to me and i want the best result

Motus comes with one wavelengths. Both Gentlelease Max Pro & Duetto MT EVO come with 755 & 1064 crytal wavelengths. But Gentlelease can emit one wavelength at a time whereas Duetto can emit both wavelengths simultaneously. Candela has higher power so enable faster treatment, & thus require special plug, power outlet, dedicated higher power electricity supply. They r all efficacious. It comes down to the quality of distributor supports & etc.
