I just received this item and I can't wait to use it. Delivery took 3 weeks. After unboxing it, I got it up and running for about 2 hours. I loved it at first I was so happy to get my first random orbit sander. This made grinding easy. Easy navigation and light weight. I couldn't believe I waited so long to get a random orbital sander, such a time saver. However, after 2 discs, part of the velcro on the grinding machine completely detached from the cloth particles of the disc pad. I used high quality Diablo discs so I'm not sure if this is a grinder or disc fault. I've tried putting a new (3) disc on the Velcro but it keeps falling off and won't attach properly. I need to clean the velcro to attach the new disc. Another issue is that the vacuum bag could have been a bit better. Dust collects on the grinder and around the battery nozzle. I cleaned it thoroughly when changing the battery. But you know, I like the model with a cord better. I don't want the dust to damage the batteries or overheat the grinder. This is my first proper random orbit sander so I may need to look at the maintenance and upkeep. So far I have a feeling there will be a lot of cleaning, more than I expected. Especially with velcro. Will let you know about the update as soon as I finish my furniture project and use it longer. However, I would advise considering the issues I was having after only 2 hours of use before purchasing this item.
