Using massage gun for ballbusting?

Has anyone heard of a massage gun such as this: https://www.amazon.co.uk/ALDOM-Massager-Percussion-Cordless-Professional/dp/B086VHWK2T/ref=mp_s_a_1_4?dchild=1&keywords=massage+gun&qid=1593291036&sr=8-4 or this: https://www.amazon.co.uk/FYLINA-Handheld-Noise-Cancelling-Indicator-Adjustment/dp/B07YK9ZC89/ref=mp_s_a_1_5?dchild=1&keywords=massage+gun&qid=1593291036&sr=8-5 being used as a (self)ballbusting tool?

You can check out some videos of them in the reviews. It seems like they can deal some painful hits to the balls, but would it be too intense? Or too weak? Maybe someone in this community happens to have one? :p
