Have this tool, it works great. There is a slight delay between pulling the trigger and firing a nail, but not enough that it’s bothersome. I think it actually works better than the more expensive Milwaukee – while the Milwaukee doesn’t have the delay, it has overheating and kickback issues.
This includes the higher-end Ryobi fast charger & the lower-end Ryobi Lithium-Ion battery (no fuel gauge, slightly lower capacity, but fine for this application).
