Highly recommend the SleepSpec glasses. Not only is the product incredible, but their customer service is also amazing. For the first time in a very long time, my girlfriend is able to sleep a night through and I am able to fall asleep in under 20 minutes (before I would take over an hour to fall asleep).2 nights ago, while putting on my glasses, it snapped down the middle. I let SleepSpec know and within 2 days I had received a replacement. Carlotta from SleepSpec was amazing to deal with.We have had a great experience dealing with SleepSpec and are definitely recommending the product to all our friends and family.Thank you!
