Review on 💧 White SteriPen Classic 3 Bundle: UV Water Purifier with 40-Micron Pre-Filter for Enhanced Water Purification by Michael Gutierrez

It's bulky - that's my only major complaint - and that both diodes have to touch the water for it to work (so if your glass is smaller than the tip , i.e. the plastic handle cannot be cleaned). Accessories are good (can be attached to the bottle). Battery life. With a set of four AA alkaline batteries, the Classic 3 will clean up to 50 liters or charge the Classic 3 with lithium batteries and clean up to 150 liters. With a lamp life of up to 8,000 liters, you will drink safe water for over 7 years!
