it seems function, even if SET UP button doesn't seem to work..
Product is decent, have to take Blood pressure atleast 3× in a row, for an average close to accurate reading, I find that if you press the part of the band that weaps on to the wrust with the sensor, the fevive gives a better reading! they should combine a finger orong to place on finger with in the same devive, at a similar price to consumer! this & all products purchased on ali express should be a little above wholesale or midtail, no close to retail ! But people are getting greedy & perhaps it is not even the vendors fault or 50/50 of the blame! in greed ! Ali Express should only release the money once a customer received oroduct & give 10 days for cleaning /sanitizing & testing device or product, however, the funds get released immediately ususlly to the vendor & when things are slowed or logistics changed several times, even winds up getting received way oast the guarantee date of delivery & the vendor 1st extends the purchase agreement for their benefit not the consumer!
When vendors extend the purchase protection, it is usually because of their late delivery, then once it shows as received, even though it is ni lt evenn at the post office, because this has happened with other products & I know my post man fo 30 years! the vendor then quickly wipes out protection purchase & dose not even give chance for a dispute or return, if the product is damaged! ALI EXPRESS SHOULD OPEN UP A REAL CUSTOMER SERVICE DEPARTMENT, TO PROTECT & HELP THE CONSUMER FIR MORE HONEST OR TRANSPARENT VENDING! ALSO, PEOPLE IN THE U S.A. SHOULD NOT BEALLOWED TO VEND PRODUCTS ON ALI EXPRESS AS THE PRICE IF A PRODUCT BECOMES DOUBLE THE COST FOR A CONSUMER & THE ONLY REASON FOR PURCHASE IN CHINA IS TO SAVE MONEY & GET GOOD PRICING ,FIR EXAMPLE IF I WANTED TI RESELL HERE IN THE U.S.A. AT A GOOD PRICE & BEAT COMPETITION! THANK YOU, PLEASE GET YOUR ACT TOGETHER!
