Anyone got a PuttOUT Deluxe Putting Mat?

Interesting, and I actually did wonder if it's something to do with the fibres. Maybe I'll give it a vacuum and try again!

I have tried it on a couple of different rooms of my house and in different directions and it seems to happen regardless, so I don't think it's the floor.

Any of you guys use the Pressure Putt Training Aid with it? Worth an investment?
