I may be a different story. But I've had nothing but healthy, long lasting toys from EE.
I bought my first Equine toy from them back before they even used Latex. It was some crazy black rubber that smelled weird, but was nice and soft.
Skip forward about 5 years and I see that they have upgraded to platinum core silicone, so I bought a wuffamute in Large. The toy design itself was strange with a TINY base that always fell over. But I've had that toy for something like 10 years now without a single problem of fading, cracking or other wear.
THEN like the mentalist I am. I went and bought the biggest Equine toy they had. The Jackson. And I have only one lasting complaint about that one. Their firmness/softness is WAY different than Bad Dragon. Because I ordered my Jackson from EE in Medium firm, like I used to do all my toys. But it is SO stiff. Feels closer to plastic than silicone. And it is far to spendy to say, "oh shucks, guess I better reorder it in Soft!"
But even that Jackson recast is something like 6 years old and has absolutely no wear or tear, dispite spending most of its life in a storage box.
