Produto de qualidade, mas atendimento ruim O produto é bom e atendeu às expectativas. No entanto, o atendimento do vendedor foi péssimo. Não enviaram a nota fiscal e, mesmo após várias tentativas de contato — tanto minhas quanto da Amazon —, não obtive retorno. Se você precisa da nota fiscal, não recomendo comprar deste vendedor

These things are great and well worth $25 if you are a "do it yourselfer". This is the second one I bought, because the first is in another state. The beeper will find freon, even on R1234yf, as I tested it with the can. It found the leak on my R134 on my Toyota last year. And, using the blacklight, just found the leak on my GMC Sierra, which comes precharged with fluorescent dye. (below) Didn't expect much for the cost, but they really work.

Vraiment très bien pour le prix , semble assez précis et très efficace

conforme aux conforme aux attentes m'a permit de détecter une fuite sur la valve

fonctionne biens reste a voir la duré dans le futur
