Think here is the best place to drop some experience.
TT equipment from aliexpress + DHS + big promotion = the worst quality control.
Prov H3 OS 38 2.2 - measured hardness 56 degrees, sponge 2.05mm, 68.8g uncut with foil. Dents in the sponge, it is possible to be a commercial version, but cut as provintial. My old H3N OS 38 was 52 degrees before boosting and 4 grams lighter.
Prov TG3 BS 39 2.1 - measured hardness 62 degrees, sponge 2mm, 74.3g uncut with foil. My old TG3 is softer, 59 measured, but is marked from DHS as 40. So the new one must be 41.5, not 39.
Prov H3 BS 39 2.2 - measured hardness 55 degrees, sponge 2.2mm, 73g uncut with foil. Same as my old one.
The level of stickiness for the rubbers is low, same as other old H3s I have, red is the stickiest.
I pay a total of 70€, so probably don't need to complain, but I was not prepared for stat distribution as items from Diablo 2.
