Review title: Open the box and wont turn on
Product review: I bought this tester when I opened the brand new box and turned on nothing happened, I looked at the manualand tried changing the batteries and nothing happened, maybe the fuse but when i checked to see the fuse it seems ok, so i called customer service and they said that I had to send it back... but i live in Costa Rica and shipping it back will cost me more than buying it here... so be careful it might come defective!
