Overall, it seems to me like a powerful machine. A few observations:
1) Where the tools connect, it's good to grease the joints because they get stuck and don’t come out easily. Also, be careful with the tightening because it can damage the clamp. It needs just the right amount of tightening.
2) The chain for the saw needs attention when tightening. Not too tight, just enough so that half a tooth rises when you lift it with your hands. After the first use, it loosens up a bit, so keep an eye on it.
3) The lawn mower is decent, but it's better to add a shredder with 3 teeth. It makes a difference.
4) For someone like me who has never used such a tool before, it gives you a workout.
5) Earplugs, a protective mask, and shin guards ARE A MUST!

In general, it seems like a good little machine to me.
