Magnification help

hello everybody,
i was struggling with insertions using 3.5x deental loops, i cant see clearlly the entrence of the follicle thus i mostly feel the sting (so no proper insertions?)
i ve read that microscope with bigger magnification can help
my questions are :
-how much does it help ? is it game changing
-and does this microscope wich isnt very expensive seems legit ( Rf4 Dernière Version Stéréo Trinoculaire 7-50x Microscope Rf7050tvw Support De Flèche À Double Bras - Buy Phone Repair Microscopes,Mobile Repair Microscope,Mobile Repair Microscope Product on ) it is used for Mobile Phone Repair i am not sure that it can do the work for the electrolysis (pros’s opignon much needed)
