I just picked up the 3 pack and had a chance to use them for the first time this weekend. Here's my take:
- dual action spray and nozzle heads are unmatched in quality
- the adjustability of the nozzle is fantastic - fine mist to super strong direct spray
- I didn't find the bottles to be to large to handle
- the tube insert is long enough to have a couple of sprays while the bottle is upside down (like at 12 o'clock on the fender wells)
- I filled a couple bottles with detail spray and all-purpose cleaner to start with (not sure what my 3rd product would be at this point - perhaps waterless wash or green wheel cleaner ... high use product I use every time)
- the detail spray tested the fine mist functionality. Very light, thin spray pattern. Didn't drip down the vertical surfaces like some other sprayers do. I suspect I used less product than the normal spray head (no scientific test though). My microfiber seemed "less wet" than with the other sprayer nozzle.
- the all-purpose cleaner tested the direct stream spray functionality. I was able to fully coat the inside of the fender well very quickly. The spray also reached the "back" of the fender well without much effort. I was also able to saturate fender and tire brushes much more quickly. I used more all-purpose cleaner with the direct spray setting, but I'm OK with that if it is degreasing the target areas appropriately (and the cost factor is not as important as something like deep wheel cleaner)
- definitely faster
- definitely less hand fatigue
- obscure observation here in Colorado: because it was windy this weekend, these product bottles stayed upright sitting on the driveway surface because of the larger base circumference. My other traditional bottles blew over. Not a deal breaker by any means, but every little thing counts.
