K&N, more expensive than Honda, (~$17 vs ~$13) had a batch with spot weld control issues on the 17 mm welded on "nut", resulting in oil leaks.
The below link is no longer valid, but K&N did own up to it and issue a recall.

Hiflow also makes a filter with the 17 mm nut, apparently with the same spot weld control issues.
Best to use a cup wrench type spin on filter.
K&N had other quality control issues. For example the cartridge type on my Yamaha TW200 had issues with glue blockage of one or more of the 4 holes on the end of the filter, thereby reducing or completely blocking flow.
I used them, as I believe the pleat quality to be good, however, I carefully inspected before using.
They were a good price at O'Reilly's and I only had to send back one.
Polarizing? Yes, it can be.
I fully expect that Jambo was sincere in his belief that 2T oil would serve well in a 4T application, if there was no clutch slippage issue... and that may be true; if the motor is never run faster than a 2T application, perhaps 6,000 RPMs
But I also do not think that the potential problems are worth the minor cost savings in the short run.
