I have had a couple of these lights for over a year now. Keep one in the car and another in the house as my go to light. So far so good, no issues as of yet.
From what others here are saying, the 220 lumens max output is greatly exagerated. However, i find it to be sufficient to use as my EDC.
For the money I spent on them ($25), the features, and the ease of use, i think it is a good buy for someone on a budget.
