Review on ⚡️ High-speed 4 Bay 18650 Battery Charger for 3.7V Li-ion TR IMR 10440 14500 16650 14650 18350 18500 16340(RCR123) Batteries - USB Intelligent Universal Rechargeable Battery Charger by Marshall Lindner

Everything worked perfectly from the first charge. When I took out the batteries, the spring pressing on the battery broke off. Now it only charges 3 batteries. Also, there are 2 color indicators to show the charge. One burned out. It took 1 full day and then something went wrong, hopefully it lasts. Update 4/14/2021: Today I looked at the charger and decided to take it apart. I already bought a replacement so it doesn't matter if it breaks. 5 screws found, the 5th is under the sticker on the back. Then he opened it and pulled out the pen. Then I bent the spot where she holds the quill so that doesn't happen again.
