It works!
Something so simple & cheap has fixed it! 2 new battery's & the AA looking at it & could not find what was draining my battery.Its been absolutely brilliant. If im not using my car for a few days I switch it off. It's a faff keep lifting your bonnet up & switching it off every time but not as bad as trying to jump start your car in the rain.

Fits on the negative post
If you're looking to isolate the positive post, this one won't fit on the positive as it is sized for the slightly smaller negative post. Even though isolating the negative is typical on car disconnects, this ought to be mentioned in the description somewhere as some may be looking, for whatever reason, to isolate the positive side.

Plug and play. Very simple. Does what it says on the tin
What is there to say? So far it works reliably. Installing is very very easy thanks to the design. It is easy now to disconnect vehicle battery for storage.

Very bulky
Does the job fine, but it requires lots of room around the battery.

Perfetto!
Ottimo prodotto per sezionare un impianto. Nel nostro caso lo abbiamo inserito sulla batteria motore così che quando il camper resta fermo nel periodo invernale possiamo disattivare la batteria.

فكت ازمة
عندي سيارتين وحده فيهم قليل استخدامها وتفضى بطاريتها كل فترة وشفت اصحاب القوارب والجت سكي يستخدمون هذه القطعة لانهم نادراً ما يخرجون القوارب للبحر. سعرها مناسب وتركيبها سهل للغاية اشبك طرفها جهة السويتش الاحمر مكان كيبل بطارية السالب (-) واشبك كيبل السالب في الجهة النحاسية للقطعة وبعدها حرك السويتش للعلامة الخضراء لتشغيل السيارة او للعلامة الحمراء لفصل البطارية
