"Been with Semapen for a couple of months now and have seen some wonderful results. I started on 95.6kg and this morning already down to 90.4kg so yes really excited. Have a target weight to achieve which I'm well on the way there but my confidence has improved and im really happy. Customer service has been great, response times excellent too. Nothing negative to report back as of yet. Many many thanks to the Semapen team"



"Been on semapen now for 3 weeks. The honest truth is I wasn't expecting it to work but it's absolutely amazing. I've already lost 8lb and having the app and scales to follow my progress is helping to keep me motivated. I never expected it to be this good. I feel amazing everyday. Highly Highly recommend and excited every morning checking my new weight."
