    Significant defect after 1.25 years

    Significant defect after 1.25 years
    I bought this item new from Amazon in June 2016. I used it probably 12-15 times over the past year and 4 months. I turned it on to check voltage on a thermostat yesterday and the LCD screen was very faint unless I view it from an extreme angle. I figured, no big deal, it must be the batteries. Unfortunately, it does the exact same thing with new batteries. I called Innova and spoke with their tech support. They said it sounds like a defective screen and a flat rate repair on it is $89.99. I paid less than that for the unit new. I asked if they could repair at their expense and they said it's out of warranty (1 year), which is what I expected. I asked if this was a known problem and the tech said no. I am not the type of person that buys products that go defective near their warranty expiration date. I will give Innova full points for at least having a phone number and answering the call (I was on hold less than 5 minutes). But, being it's the only time I have purchased from this company, it's the only experience I have to decide if I will do business with them again. The tech's suggestion was to buy another one. I think I'll try another brand. My $19 multi-meter from Radio Shack still works after 15 years, so I guess I could use that.
