Car ESC from Bidproduct

Hello,
I am a new hear and I am from Luxembourg, a little country in Europe(my English is not very good, so be nice) and I came here because I have a question, of course. So, I bought a Thunder Tiger ST-1 Roller chassis(no Motor etc) and I want to do Brushless in it. Because I'm only 16, I don't want spend too much.
I want to buy this Motor and 5S 4900mah Rhino Lipos from unitedhobbies. But unfortunately, the ESC is the expensivest on the Car. I looked at the Mamba Max ESC, but it only can work with 3S(4S without BEC). So, I looked more...the Mamba Monster Max is too expensive, an the Losi ESC too. So, I searched more an found this: Link . I mean the Yellow ESCs, "Two Way Brushless ESC 80A for Car with Break With BEC."
Does anybody has bought them and can say something about them? Are they good? And does the Brake works well(the Most important, otherwise I could use a Plane-ESC). I would be very happy if somebody could help me

best regards from Luxembourg,
gigi
