Just received the GVI anti vibration pads in the mail-read alot of positive reviews. My machine does not walk, just vibrates, resonates in floor (LG WM20301H). However it appears these pads do not slide. My washer/dryer set is in a large closet with limited access on either side. If I need to get behind them for any reason I don't knoe how I would move them out if I couldn't slide them. Any thoughts or advice? Also, do these pads really work ( I have seen the infamous electronic vibration meter video). Thanks
