Electronic flasher upgrade

Not sure how fast should the turn signals blink by default, but I want mine faster and reliable.
Can anyone give tell me simply which electronic flasher is a good reliable upgrade?

Is Tridon/Stant 552 a good one?

Check you haven't got them swapped over. The turn signals will flash slowly (or not at all) if the hazard warning flasher has been installed din it's place by mistake. Or perhaps bulbs have bee changed for lower wattage or LEDs

I used some more modern ones from ZZ-R1100 I think. These are small plastic units and I think they have electronics to control flash rather than bi-metal strip.

I see it's a FE246BH flasher relay. Will research that. Thank you!
