It's been 2 months since I bought this product. Appraisal: 10 used batteries and same finding in all cases. At first, the power is the same as for brand batteries, but the charge does not take long. They wear out much faster and one must therefore change more often. In total, both buy batteries more expensive but more reliable. We can thus be certain, for example, that the spare torch will not go out after an hour.
