Bests & Worsts Reviews from Amazon

1/21/18 First unit received Jumps like crazy and is unusable, waiting on replacement= holding up project. I've never owned a Wen product before, it was cheap and as the saying goes... First impressions are ok on ergonomics, could have used less rubber to lighten handle, dust vacuum hose seems durable though a little heavy as well, mechanics of motor mount seem ok. Plastics not so great on sanding pad mount very thin and plastic is abs with no fiber reinforcement. The dust cover is a very poor design for movement and in my case would not recess enough for brushes on edge to get out of the way to allow sanding disc to contact surface evenly, causing extreme jumping. I removed dust shroud and the balance from motor to sanding disc is very poor, not a smooth running machine, jumps and wobbles without shroud as well. It seems like they spent more on design of handle and hose material than the part that really matters most, weak point is motor assembly and disc balance. I'm the type to buy a tool and DIY rather than pay another person to do the job. I should have just rented a pro porter cable setup for $40 a day. But I thought this would come in handy and save a few bux. Will update after replacement. 1/25/18 Second unit received, I really can't understand how this product has so many high reviews, it seems rather odd after receiving two brand new units and having the same quality issues, either these people have never used a sander like this before and think this is how they operate or they are in collusion in buffing up reviews for this product.This is complete garbage, using wen sanding paper, the brush on the rim is a poor design, gets in the way of sanding pad, will make contact and melt from pad hitting it causing it to get hard and crusty and scratch, removing it makes the unit spew more dust out. The sanding pad is junk, the pad is uneven causing it to wobble and jump= calling Wen to see what a replacement pad will do from them directly- perhaps there has been an improvement from amazon stock, trying this before returning the second unit. will update. 1/29/18 Received replacement pad, however because it was packaged only in a soft shipping envelope the mail person crammed it in my mailbox causing it to warp, idk how it survived initial shipping with just the envelope, as it took some doing getting it out of the mailbox I assume the damage happened there. Requesting a replacement yet again. Product is still useless in the meantime. 2/6/18 Company is unresponsive on a replacement for their product being damaged because of the way they shipped it, attempted to contact three times has been ignored. 3/2/18 never heard from company WEN again! Submitted a couple emails nothing back. I ended up ordering a Festool 201895 Sander Backing Pad St-Stf-D215/8-LHS-E on ebay and was able to mount it to the WEN , on e b a y. It performs much better now, I just had to spend as much for the festool pad as I did for the WEN sander, but hey you get what you pay for, so there it is a working drywall sander. With the festool backer pad installed it works great as it should have from the get go! THE BACKER PAD THAT WEN SUPPLIES WITH THE SANDER IS TOTAL JUNK AND THE COMPANY NEEDS TO SERIOUSLY LOOK INTO IMPROVING THIS PART, IT IS THE WEAK LINK TO AN OTHERWISE GOOD PRODUCT.
