Personally I eschewed a machine for a set of good adjustable dumbbells and a bench and I don’t regret it at all. I don’t like machines because they allow you to cheat with bad form and that leads to joint injuries. I found that I can use significantly less weight with free weights as compared to a machine, and while that’s not as good for the ego, it’s better for my joints. Lifting weights has turned into a more yoga like mindful execution of movement rather than a grunty maximum exertion of force since I switched, and I really like it. It’s challenging to do legs, but I’ve got a bad knee and I can still do enough with my two 5-80 dumbbells to feel it the next day.

Looks like it doesn't have any way to train legs so you should probably get something extra for that. Legs are hard to train with just bodyweight because the muscles are too strong and don't get exhausted from just the weight of your body.

Can you pull the handles in the middle towards you in a rowing motion, or is it just for pushing? If not, you need some way to train your back also. Maybe back extension would work as a bodyweight exercise.

Of course it is. A single dumbbell can help you get fit at home. This has a pretty wide range of capabilities, so you're good in that regard. You're probably going to want some help developing a program that works for you.
