2 Pack 9 inch 6 Hole Hook and Loop Replacement Backing Pad for Orbital Sander Drywall Sander for Wall Grinding Woodworking

I've order these replacement pads for my 9 inch drywall sanders twice now...because I needed them, they are not perfect, but you can work with them.They r slightly out of balance...but with a bit of pressure, the wobble and bounce can b controlled and eliminated.I couldn't find any others that fit my machine, that were purfect(balanced...had "NO" wobble and bounce)...at least with these replacement pads, I could control them and continue using the machine 2 finish/complete the job 2a satisfactory conclusion.As soon as I find a better balanced replacement 9 inch pad(that needs no added pressure 2 function)...I will stop purchasing these pads and will start purchasing the better ones.The less effort needed 4a unit 2 function...the better the final finished surface.I gave this product 3 stars because, they work alright with some added pressure...but they could b much better.
