Can i get lifetime CSGO cheat license with my knife ?(+other questions)

Hello there. I am wondering if i can get a lifetime CSGO cheats license with my knife, Falchion Knife Fade Factory New, which is 115-120€ on market.
 Other questions:

Will i get instructions and advices abouti installing and using the cheat after i buy it ?

Shall i check for updates or it does update automatically ?

I read that this cheat is undetectable by VAC, 100% true ?

Questions about some features:
Skin changer: will other players see the skins i use via skinchanger ? 

 am waiting for a response, thanks for your time.

yes there is an instructions page all you have to do is download and inject

the client auto updates

undetected from vac for 11 months

only you can see the skin changer

@Mapec actually I cannot PM you because " you reached maximum nimber of PMs" or something. Btw other players cannot see the skins via skinchanger ? I mean my team mates, enemies etc.

your knife is worth 47 keys which is 93$~, lifetime Aimware is 113$+, 20$ difference

not to mention cashout fee + commission from selling it back on op skins if you want to make your money back

Any sales incoming ?
