They are South African bits, so I would think they are made in South Africa. A lot of these bits are designed for polo horses,
I think it is all very well if your horse has a normal mouth conformation that you can put any old bit in its mouth and not have to pay that much money. However, if you have a horse with a low palate, fat tongue, I am afraid no matter how fantastic a rider you are, it is not going to be happy in a jointed snaffle.
I also think that we spend huge amounts of money on saddles, saddle pads, people think nothing of spending hundreds on accessories - a lot of cheap bits aren't actually finished particularly well and nor is each arm the same length.
If it ain't broke, then don't fix it, but for some horses, bits that have had a bit of thought put into them help a lot.
If it helped my horse, I would not have a problem spending 60 or 80 quid on a bit - if I had to have something in my mouth, I would like it to be comfortable!
OP, I tried their Happy Tongue bit - didn't do it for my boy although according to the lady at the bit bank who used it on her very fat tongued horse, he loved it. Trial and error like everything!
