are they any good, or should i not do it...just got a cheapo car with air con..woo, went to get it recharged at garage, said he cant do it cos there`s no pressure in and might be a leak...ok, came home checked everything over, found the tyre type valves in the pipes were not really tight, must of leaked out of there....

rang a local garage to ask about leak test, they said about 200 quid..car was only £360, so er no....
