Don't waste your money on the LED backlight. It just makes the whole field blue and you won't see a line. This is a trick. Check the packaging as it was not packed with a packing pad. Luckily the box itself was full of foam and well packaged. So far the refractometer works well and is accurate. Easy to set up and calibrate. Works as it should.
