1. The polyclay chips are not perfect, but they are pretty darn nice chips, especially at the price point.
2. Totally uniform across all denominations, as far as I could tell. Stacks of twenty to fifty chips exhibited no visual height difference, and all denominations fit in same-mfg racks the same way.
3. The material is very difficult to break (took two sets of pliers to snap one). It appears to be a modified version of Sun-Fly's ceramic material. Imo, it's harder and less prone to chipping, has a lot more grip, with a more-muted and less-clinky sound than one would expect with a 'ceramic' based chip. They don't sound like Paulsons, but they sure don't sound like Chipcos, either. Somewhere in-between.
4. The chips are printed, and some minor surface wear and color transfer was apparent after ~severely~ rubbing two chips together (one white, one red -- figuring this was probably worst case scenario). Casually shuffling a mixed-denomination stack of eight chips for quite a bit produced no obvious wear or transfer on any of the chips.
5. There is some minor color shading differences of the rolling edges in some denominations. I think this would be less noticeable with the non-solid chip versions on this mold.
6. The rolling edge has the customary glossy-finish of most Sun-Fly ceramics, with the injection-nipple clearly evident (again, probably less noticeable if they weren't solid colors).
7. Some of the best stacking chips I've ever seen. Way above other ceramics, and even put used casino Paulson and new MD-50 chips to shame. Much closer in performance to new mint RHC chips than anything else I tested. Grip is simply incredible, given the material.
Ran two types of tests: skid test (increase angle until entire barrel starts to move due to loss of chip-to-felt friction), and a topple test (increase angle until barrel topples due to loss of chip-to-chip friction). The base chip of each stack was restrained in the topple test to prevent skidding prior to loss of chip-to-chip friction.
Below are rankings and maximum angle of the eight chip types tested (worst to best):
skid test:
~ 3rd, 11.7 degrees - new ASM MD-50 mold
~ 2nd, 14.4 degrees - new Paulson RHC mold
~ 1st, 15.3 degrees - new Sun-Fly polyclay mold
topple test:
~ 8th, 9.9 degrees - ceramic blanks (unknown mfg, suspected Sun-Fly)
~ 7th, 10.4 degrees - new Chipco ceramic
~ 6th, 10.8 degrees - new Sun-Fly ceramic
~ 5th, 11.7 degrees - used Paulson RHC mold
~ 4th, 12.6 degrees - new ASM MD-50 mold
~ 3rd, 18.0 degrees - new Sun-Fly polyclay mold
~ 2nd, 20.7 degrees - new Paulson RHC mold
~ 1st, 25.2 degrees - new Paulson THC mold
Dealing directly with Sun-Fly was trouble-free, with decent communication (confirmation and progress updates) and reasonably quick manufacturing and shipping (more than I can say about myself on either count).
I really like the chips -- and the printing -- but I will probably opt for a custom set with aligned spots if/when I order -- most issues I have with the chips would likely be resolved if not ordering solid colors.
