Found this set 20% off and grabbed it about a month ago. Impact wrench works great on either size Li-ion battery. I have rotated tires and tightened bolts during my deck build. The grinder has been a huge help. I use a coarse sanding wheel to shape the edges of deck boards and strip surface rust from my trailer. The grinder drains batteries quickly, but that should be expected and the runtime is still very adequate. The batteries perform well, but if you need to but more separately, spend a little more for the extra capacity of an XCP battery.
Have used this set for about 4 months. Impact has exceeded my expectations greatly, use it constantly with a set of HF sockets. Grinder is good too, but uses a lot of power and batteries don't last long (about 20 mins) i use the grinder for flap disk work removing rust and occasional cutoff wheel work. Batteries and charger have worked good so far but i use a 4 port charger so Charger don't get used much. Both tools feel good in hand except grinder is a bit heavy especially with a big xcp battery on the back.
Writing this review only after 2 weeks of use but it did exceed expectations. I have air tools that I use regularly, but when trying to take off bolts at the junkyard, the impact has exceeded my expectations at this price point. The battery consumption is huge compared to a brushless impact but I wouldn't pay much more for that unless you are using this for hours on end without being close to an outlet fto charge the 2nd battery. I haven't really tested out the Angle grinder yet.
Good for the job
Great machine good quality
