A little trouble with the first shipment but could have been a ups issue. as far as the sander it works great. But expect a lot of set-up time. I probably spent a day on set-up but I'm very precise about my tools. Put casters on this bad boy, it weighs a lot. As far as sanding, it does an excellent job, super smooth after a couple of passes. Mine came with 60 and 100 grit paper on first and second drum, I changed it to 80/120 to get it ready for the random orbit sander for the final surface. Dust collection is not the best. I have it right beside my 1600cfm collector with 2 hoses, it gets the fine airbourne dust but leaves a lot on the wood and conveyor to fall off on the floor. The main thing this beast could use is some way of determining the set-up height. You have to push your wood in with the machine off and adjust by feel. It has plenty of power, never had it even grunt the least. The sandpaper attachment doesn't keep the paper tight enough for me so I spray the back of the sandpaper with contact adhesive just before rolling it on and then tape the ends with packing tape. I still have 24" of sanding because the rollers are about 25" to 25 1/2" long. I've had the machine for about six months and had no trouble. I find myself running everything through it from boards to gluded panels-(which I bought it for). Leaves edges square too. If your like me and can't justify a wide belt sander, I would recommend this powerful sander, and buy it again.
