The pad has the same number as the one I need to replace however the model number is not listed. Mine model is RO 150E Plus 120V. It looks identical. If I buy it and it doesn't fit do you return the full amount paid.

This is not the correct replacement pad for your Festool RO150E, which is from before 2009 roughly. That sander uses the same pad as the Festool ETS 150, which is a 150mm (or 6") pad with a bolt in the center. Here's a link to the direct replacement for your original pad.http://www.toolnut.com/festool-498987-fusion-tec-6-150-mm-sanding-pad-soft.htmlYou can review our return policy using the link below.http://www.toolnut.com/policies.html#return-policies
