I like Ridgid. They have a lifetime service contract/warranty. If you go online and register the device within 90 days of purchase. I have pretty much gone to Ridgid because of that. I have several DA 120 volt sanders and one 18 volt DA sander for when power isnít readily available. I had one of the 120 volt DAs reworked last month since the motor wouldnít hold a steady RPM. They come with a 3 year warranty and they just give you a new one if you have a problem. After 3 years they will try to repair it and if they canít they will give you a new one. If the package includes batteries they are also included in the service contract/warranty. No affiliation. They have a dual voltage fan that is awesome. It will run on low for over 48 hours on a 4 amp hour battery or you can plug it in with an extension cord. We keep 2 of them on the boat and move them around to wherever we are sitting. Also the fan on low is dead quiet and moves enough air for my wife to sleep, she want a fan on at night.
If you are one there is no explanation necessary.
If you arenít one, there is no explanation possible.
