After waiting for two months or so, I finally received the 1/48th scale treads for the Tamiya Tiger I from Armour Workshop and these are an absolutely terrible product.
Here is the PMMS review, which I can tell you is a completely inaccurate description of the product I received:

The links are small and cast in flimsy, crumbly resin. They are poorly molded and have lots of flash and irregularities where the teeth are supposed to join, and when you try to excavate the resin out, the link breaks, or the teeth break off as you manhandle the tiny link.
If you get the link cleaned up so it fits, and it’s not warped (another distinct possibility), and you go in to get the thick resin flash out of the teeth, the tooth is almost guaranteed to break off.
The pins generally fit very poorly, although occasionally you get the odd well-cast link and the pin slides in ok. These are outnumbered by the links that break, or that are warped so that it’s functionally impossible to slip the pin through.
Look at it this way. It took me an hour to put four links together. At this rate it will take me about forty hours to put all 200 or so together for two lengths. Part of this was working on a link, cleaning it out, cleaning out the connection points, only, if it has not broken in the meantime, to have the pin not fit through, or have a tooth break off as I handle the link. I broke more than I connected in that hour.
Also keep this in mind. It took me an hour to build two full lengths of WWII Productions resin Panzer 38t treads, which though 35th scale are much smaller and more delicate than these, but a well cast and quality product.
It’s not worth it. My recommendation is to avoid these at all costs. I doubled the cost of the kit for a product I cannot use. I find it very hard to believe that my set of 220 links is somehow a fluke and not representative of the general products produced with this company. And now the process of getting my money back. I wonder how much luck I’ll have.
