Sorry to say that about a Meg's product, but this backing plate that comes with 5" MF kit is the worst I've used.
I was sold by the recommendation to use Meg's plate with their MF (not other brand), ended up with a bad backing plate I can't trust and barely use.
It does not hold MF discs making you to stop and re-center pad even while polishing. To 'help' it not working, MF discs comes with some fancy design on their back instead of a full side of powerful velcro to HOLD the pad where it should be.
Incredible, I also had heating and melting using MF FINISHING disc on speed 4 to wax a car with D301 and the W67 plate provided. The melting have not damaged permanently pad or plate, but it happened and the marks are there. No damage to paint or anything, just the back of pad and face of backing plate.
Now I have to use my MF discs with Meg's 6" (W68) plate that comes with Meg's DA, it's an exact match, so one have to beware not having security margin. However, velcro hold pad centered much better.
Now I have 8-10 MF discs that I don't use because plate provided is bad.
I can't recommend other because I haven't used LC 5" plate, but if you can, avoid Meg's plate that comes with kit at all costs.
Look here:

It has 2 reviews saying what I'm saying. I don't blindly trust reviews since that may be caused by user error, but in this case, I've faced it personally.
If I could go back in time, I would never ordered this plate.
Again, really sorry about meg's this time, I like, use and support their brand.
Try to search for an alternative or you'll be one more with problems regarding this backing plate.
Kind Regards.
