Its super late, but you might want to try high quality sprinklers from DripWorks.com
https://www.dripworks.com/drip-irrigation/sprinklers
They also publish catalog every year which I receive. https://www.dripworks.com/content/dripworks-2022-retail-catalog.pdf
Most of the stuff they sell is made...
I ended up buying Ez-flow injector from DripWorks.com Thank you for recommendation. Great people and amazing call center service and guided me on the process.
