see if you can find the actual model number cause miotuyo's all look the same but the model numbers are different. And your looking at a price range of $50 to almost $200 for almost the same looking model as the one you have. That way i and you have an idea of which one it is.It should have a number that starts with 500 then a dash and then some more numbers. it will look like 500-### and some are 500-###-## . This way im not paying 100 for a 50 and you wont get stuck taking 50 for a $200.
