These batteries work alright. The protective circuitry is adequate and includes a heat sensor. However, the 18650 cells used in these batteries are only rated for 2000mAh. That makes the claim of 3.0Ah (3000mAh) dishonest. What's more, I tested both of these batteries more than once on a load tester, starting from a full charge. They each averaged about 2000mAh. When testing the name-brand version of these batteries, I saw average results of nearly 3200mAh. These batteries only cost half as much, so they aren't really a bad deal (even considering their reduced capacity). The dishonest claim of 3.0Ah is only going to lead to disappointed customers when the batteries die before they expect them to.
