Do not buy from Aliexpress if you want to get what you ordered - the past 5 orders have the wrong products shipped. The sellers only want to give you a discounted refund - they still make money and you are out of pocket !! Here is my Dispute: Appeal to dispute on Order number: 8120233919631471 Let me ask you this: Would you buy a Watch that didn’t give you right time of day? Or Day of the week? It is the same with this item (LIGE Smart Watch)– the seller says that it will give you measurement of you Heart Beats and a measurement of Blood Pressure. But the LGE measurement is totally wrong - not even close! When I compare the Heart Rate (beats per minute) with an Apple watch and a Home Blood Pressure tester (Omron) – the Apple and Omron are within 1 Beat per minute with each other. The measurement from Omron is 102 BPM - Apple test results are 103 BPM - LIGE is 62 BPM (BPM = Beats per Minute) That is an error of 40 BPM or a 40 % error in measurement!! Blood Pressure measurement: LIGE READING: 114/76 (Normal) vs Omron reading of: 130 / 98 (hypertension) Hypertension is very bad – dangerous – you can not trust the LIGE reading if you do you would have a heart attack from the false reading !! Therefore I will not use the LIGE for anything it will be thrown out – as it is junk! How did you get to: Final resolution: Partial refund 15.51 CAD without returning goods – I would return the item if it wouldn’t cost me so much money to do so. About $46.00 to ship the unit back. Even if I did ship the unit back there is no guarantee that it would get there in time – so the seller can still refuse to return money. The seller gives false description of how the product works in the advertisement on AliExpress – then replies do not compare the reading of the measurement to professional equipment - they know that LIGE is not working properly! If the seller would say in the advertisement on AliExpress that the LIGE has erroneous readings that could be off by 40 % I would never have bought the LIGE – nor would other customers !
