Good quality. Worked for what I needed it for (tube twist). He also did a decent job. Ordered and received quickly. Didn't have to pay either. I won't be using it every day or even every month, just occasionally and for that purpose it should last quite a while from the look and feel. Can't argue with the price and fast delivery.
For the money I think it might be worth it. It looks well built but the bearing inside is like a kingpin bearing that wears out at one point and when you spin it, feel dents worn in a race. I don't think it will last long but I only use it once or twice a year and I use a slow rotation because I'm new and trying to be safe. I wish they had charged $5 more and used better stock. 3 1/2 stars.
I bought the model in size MT4. The bearings on it are very smooth and it turns very easily on what I got. Other reviews that have mentioned bad bearings say they are for the MT3 model, so maybe the MT4 is better, or maybe I just got lucky with a good bearing. It's definitely very good for the price. MT4 Dimensions: 2.125" nose so a 2.25" bore/bore stock would be the minimum size you would use for a 0.5" diameter at most of the head. Standard morse taper 4 shank.
