I'm so happy I bought this nail onychomycosis laser device. I only had fungus on one of my toes, so it wasn't too time consuming (there were multiple options). It's a process and you have to be consistent and patient. But if you can do this, you will see results. Some other great things about this product is that the battery is very durable and I probably only had to charge it twice. And its very easy to use, and the timer is also very convenient. The ability to treat multiple toenails is an advantage. If you've been struggling with this issue, you should give it a try. Much better than drugs and expensive doctor visits. I can't express how grateful I am for this company!
