Perfect service
I ordered a wrench and an on-off switch for my old Makita sander. The costs were reasonable, and I received them quickly. And they were correct.

Sander was lent to a relative who lost the wrench which made the sander useless without it.
I was simply able to use the wrench to remove and replace the sand paper discs now.
