I bought a Milwaukee tools combo kit and got a 6.0Ah battery on redemption. Very fast delivery, and the tools are awesome.

Had for a month or so, good run time and power and re charge time is good too, only issue is they are quite long in the impact driver and I find that the battery hits the surface of what I’m screwing into before the screw is driven home. I prefer the 5amps for impact drivers, but the 6amp is great for everything else
I was Milwaukee fan and like the tools so much .but Sydney tools warranty take time too long.hopefully Milwaukee can improve this.
Works on all M18 tools, but you get the best results on the FUEL range which maximizes the high output, giving you that extra power and longer tool time. Also has the fuel gauge battery level indicator on the front so no guesswork. Avoid cheap knock offs, they don't last. Genuine is the way to go if you're serious.
Have purchased several of these 6amp highout put batteries I get great run time on them without the additional weight of the higher amp batteries
I got this as a redemption. Quite pleased how it lasts in the sawzall, but a massive difference to the 8ah high output in the blower.
This is the best tool brand for your buck. Lasts over 8 years with continuous use still provides long use times and powerful torque.
I have had the kit for approx 4 months. The batteries have cracked around the charge label and seem to cut in and out. The blower also cuts out
