    SteriPen is a great company! I purchased my Ultra at a retail store “garage sale” (condition: like new) but when I brought it home to test, the Ultra indicated the lamp was out. I contacted SteriPen who quickly suggested I send it in to them for service. Just got it back this morning and I’m all set to go! All of the service technicians were very helpful and prompt when emailing back and forth. And they charged no service fee!! All I had to do was cover my return shipping.
    Thank you for a great product and great service!

    The SteriPEN is an absolutely essential travel tool, especially in developing countries where sometimes even the bottled water can’t be trusted. My husband and I have been traveling around SE Asia for over 8 months, we use our SteriPEN every single day. It’s easily one of the most important tools in our bag. You can read our full review on our blog here: . I will never travel or hike without a SteriPEN again.
