I am always sceptical on buying certain products as I know how I use them my self, I have high expectations on alot of things, and these replacement pads met them, sounds silly but they have to stay in place in a harsh work place, high and low temperatures, and many have just gummed up or fallen off. Your product is of very high quality and packaging was as well, speedy delivery, ease of use, great job, I'm now one more customer for life thank You!
