4" plate
Excellent can run my 5-5.5" pads easily
ProsMultiple pads usage
Backing plate
Great product
Low quality, do not buy
These 2 plates developed wobble first time I used them on my Flex DA, the second time I used them one of the plates cracked, so I tossed it. The third time I used remaining plate, the center mounting hole cracked when I was polishing my car. What a junk! I contacted Autogeek, but never heard back from them.
ProsNone, completely useless and unsafe
ConsLowest quality possible!

This item is junk. Purchased one with my original Flex a year ago, failed a year later. Purchased a new one to replace that one and it failed with 5 minutes. Literally 5 minutes I couldn't believe it. Contacted AG a week ago and haven't heard anything. Will be emailing them again. This thing is junk, both failed at the base where the bolt connects to the flex.

Quality issues
My first 4" Lake Country backing plate broke down at the end of the first use (approx 3 hrs), so the Lake Country people kindly replaced it with the new one. This one lasted a bit longer, about 4hrs, but that was it. The original Flex 5.5" plate works fantastic, after hundreds of hours of detailing.
ProsCan be used with various polishing pads
ConsMade of low quality plastic that doesn't last long. I suggest that manufacturer either improve the quality of the materials used (to match the quality of the machine), or discontinue this product immediately.
