Is lonsdor k518ise worth the payment?

I think the value of one machine is to help people make money, if Lonsdor K518ISE can help you make profit, it’s good tool.
There are many car models are free update lifetime (about 38pages update in October, 2018 and only 10 pages of models charge if you need)
