I've been a Singer customer for over 40 years. My last serger lasted over 20 years. I replaced it with this one. The accessory bin (also the piece you take off to do smaller things) doesn't come off without turning the machine over and prying it with a screw driver. Having the huge bump out makes threading the machine impossible. The lower looper is the most aggravating thing in all of sewing to thread even with the bin off. Unlike my previous machine, there is no way to get to the hole where the thread has to go on the looper arm. There's a way to get the thread back there and hope and pray it does what it's supposed to do, but you can't see because it's inside the machine. Lastly, the way the 'hooks' are that you put the thread under where it comes off the cone allow the thread to wrap around the wires and become jammed, causing the thread to break and have to rethread the machine over and over again. Also, the loops hang out over the fabric edges once sewn. I've noticed this happens after sewing thick pieces of material, and going back to two pieces of cotton makes it hang out over the edges. Rethreading the machine (the horror described above) is the only way to fix it, until the next thicker layers are sewn. I've never ever considered buying another brand until now. I would never in a million years consider recommending this machine to anyone. All the local places that service sewing machines charge a lot more for Singers, and also give you a lectures about buying one. I guess this is why.
