I ordered this product for weight loss.. Just after placing the order the fitkit customer care called n asked me to update them on whatsapp with the picture of the invoice.. It got delivered within the expected time. As soon as it was delivered i shared the invoice on whatsapp with fitkit.. I got the call from the fitkit customer care for free installation next day.. 2 guys came n installed it within 20 mins.. Using it since last 10 days.. It's very nice.. Very good quality.. Don't need electricity.. Doesn't make noise.. U can adjust the resistance n calculate the speed time calories etc in the meter.. Don't think much.. Just go for it..
