Many Israeli Chareidim use shavers also. R’ Shlomo Zalman Auerbach ZT”L actually permitted certain shavers that even R’ Moshe ZT”L did not.
Someone I know very well showed me a particular shaver he bought. I told him that according to what I understand from my Rov (who is a renowned posek), it may be problematic. When this person showed it to the same Rov, he said that indeed according to R’ Moshe it would be problematic, but according to R’ Shlomo Zalman it would be fine!
