I need some advice about buying my first roulette computer

I have seen the evo 12V and talked to Mark Howe, he told me there is the evo 14V now.
Has anyone tried one of his computers? Should I buy one?
Thank you!

Just watched Mark Howe’s video predicting with his roulette computer. It is not very sophisticated, as you can tell from the price. There is no way to give feedback to the computer which is essential. Forester’s computer has more features.
