Great value in batteries.
Are these the best AG13 batteries ever? Nope. I would not take them on survival critical trips, but for the low price, good reliability and good shelf life they are the clearly worth the price. If you need Wagu beef for your burgers, these are not for you, but if USDA Prime is good enough for your daily dose, you should look into these.

Cost effective product
I have used these and some US made name brands, these are not quite as good, but a fraction of the price. For the low price, one gets a large percentage of the quality, so it is a good trade off. Will they last as long? Will they do as good a job?
To the former, I don't know, but my guess is no, they will have a shorter life on hard, tough work. But on softer work (like HRS), they should last for years.
Will they do as good a job? Nope, but again, 90+% as good may be good enough.
For a tool and die maker working on hard steels most work days, they are a poor choice. For a spare set, they are a great choice, for a hobbiest, probably good enough.
Remember, getting 25 years out of a set of needle files at 70 years of age means a lifetime of service, getting 10 years at age 21 is not, but if they break, wear out or get "permanently borrowed" they were cost effective. The really nice set will last a lifetime, but are many times the money.

Great unit with limitations.
2 of 2 found this helpful The worst feature is the lack of graphical display of the pulse. The display tends to wash out in direct sunlight. On the other hand, it works reasonably well with the Android app (the app lacks some features), but it does a good job for a low price. I checked it against units at the doctor's office and the emergency room, it was within 1% of the expensive machine readings, within quantizing error is good enough.
I would not recommend it as a professional machine, but for individual patients, it is a good choice. I can not discuss battery life as I am on my first set.
