We’ve had these for more than a year now. (eG-friendly Amazon.com link) Note that the price depends on your color choice. (I see there is also a stainless steel version available now)
They work well, clean up between refills very well.
The only trick is to be sure there’s no excessive oil buildup on the outer “nozzle/spray area” and to firmly and deliberately squeeze the handle, when correctly used they dispense 1/4 teaspoon of oil per squeeze.
Baking Spray, in my experience, refers to this or similar, (eG-friendly Amazon.com link).
