Yes, I received my Mint Lp protractor late last week.
I guess my assessment is not as glowing as others who have posted. First up, it works and works well so no issues there.
I am not sure about the others but my protractor has drops and marks ( under the surface between the stuck on plastic and the mirror) which made the protractor look dirty and s/h. Yip assured me this was normal as the top of the surface was clean and smooth - which it was.
I find the Wally tractor is better made, has both baerwald and Loefgren alignment choices. Mint only has Baerwald as he says it sounds better. Wally gives you the choice of aligning to either and you choose which one you prefer.
The arc and null points on the Mint are on the plastic sheet with pen or similar, whereas the Wally tractor has a laser etching on the mirror for the arc, baearwald, loefgren and null points. This actually makes it a little easier as your stylus will sit in the etched groove ( it is not deep enough to damage the stylus) as a small nudge will move it off the etched line.
With the Mint, you need to rely purely on sight of the tip of the stylus touching the arc or null point. Easy with my Dyna XV-1, maybe not so easy with my Koetsu. So alignment I believe is easier with the Wally.
Both use parallax to get the alignment of the cantilever perfect.
The 10X Lupe was a waste of money, however the 5x magnifier with light that came with the Mint was excellent.
Customer service - no doubt Yip is a lot better than Wally in this regard. Yip followed up with prompt emails so No1 as far as customer service goes. Wally OTOH is very SLOW with emails, even thou he is a very nice guy to talk to if you can catch him on the phone.
Mint vs the Graham jig. Both end up with a similar result, except the Mint gets you to a more precise alignment due to the fact that the Mint or Wally has a point and parallax to align the stylus tip and cantilever, whereas the Graham does not have an exact point to align the stylus tip so you are unsure where to rest the stylus point.
Would I buy another Mint protractor for the new price of $110 vs $149 for the wally tractor, or the new Wally universal tractor that has 13 seperate alignments on it.
I would buy the Wally, however I might change my mind if his customer service is still bad.
Hope this helps
cheers
