I can see how bad the other brands are by the level of customer complaints. The batteries and chargers I buy from RHY are awesome. It is one year and no failures.

X*T's products are cheaper but also lower in quality. I used X*T's products for a while before I knew RHY.

The battery of X*T had many quality problems. So I was able to find RHY and after dealing with RHY, the battery is now stable.
