Very happy with the bit. I've used it quite a bit and still seems very sharp. It will leave marks if you leave it in one place too long.

Used with my DeWalt mini finishing router. Works well.

Use this to level my spoilboard on a Longmill Mk2, works great. With the head trammed, no visible marks on my MDF spoilboard. Only caveat is there were "fuzzies" left behind on the outer perimeter with a .5mm depth of cut @ 1500mm/min. I am very new to this so it could be used error but could also be sharpness if the bit. Could've spent more on potentially a better bit but for the money, I am happy with this. Also levelled a slab of walnut with this bit and had no fuzz but had step over beyond the perimeter of the cut. All in all I would say I would purchase this bit again.

1.5 month update:
Have been using this bit more to flatten reclaimed hardwoods and pine slabs. It's been working excellent so long as I make sure to cut outside the slab on the final pass. I messed up big-time in a hurry and collided with one of my aluminum hold-downs. Took 1/8" off the top before I hit the e-stop and shut it down. Have surfaced a few pieces since and it's still milling strong. No marks/ lines after a cut. Maybe I got lucky but I will grab another one of these when this one is done being abused by this novice.

Works great, cuts even hard oak well, leaves behind a very acceptable finish.

Bonus points for the short shaft, valuable in smaller 2018-sized CNCs with limited Z travel.

I had a large sizable slab of live edge white oak about 9' long and 2.5' feet wide with a bow and twists in multiple areas. White oak is a heavy and hard wood. It's even harder than American Walnut so I was right to be a little skeptical on this bit's effectiveness. I started on the bottom side of the slab since that was flatter and I figured once I got one side flat, it would make it easier to flatten the other side. I made a sled for the router to rest on, found the highest point on the slab, hooked up the dust collector to my router and got started. This little, bitty bit did not disappoint. I was able to complete one side in about an hour even after shaving off only a little at a time. The blade stayed sharp the entire time (altho I would probably sharpen it before using it again). Needless to say, I'm very impressed with it. It also came with a 1/2" to 1/4" collet. I didn't need to use it but since I didn't have one, it was a nice bonus.
