Both the charger and the batteries appear to be well made with good materials, including gold-plated contacts. I charged the 3 batteries that came with this charger. They do fit my Canon SX70 HS camera, which uses LP-E12 batteries, and all batteries registered a full charge in my camera. Note that these batteries claim a capacity of 8.14 Wh, which is 29% more than the factory batteries. (Based on later comparison of video recording times, these batteries and the ones that came with my camera provide almost exactly the same run time, 111 minutes for one set and 118 minutes for the other. They are effectively the same in terms of capacity, regardless of the declared capacity.)

So, they appear to have good build quality, and they work in my camera as well as the ones that came with the camera. That leaves one important question unanswered: how many recharge cycles will they last? Unfortunately, that test should take over a year, and so is impractical.

Based on the build quality, tested capacity, and the compatibility with the form factor and output voltage needed by my camera, I give this item 5 stars. It appears to present an excellent value for money.
