Value priced, meets or exceeds description, works as advertised and is a value.
I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

Good rechargeable
Good recharge battery . Holds a charge for and acceptable amount of time in my flashlights. Will purchase again. Worth the price.

Ever so slightly larger than other 21700's
If the device you are using 21700 batteries in has a very tight size tolderance then these might not fit. They are just a bit taller and fatter than other 21700 batteries I have used. These will not fit in 4 out 5 of my devices.So far they appear to be good in use but I have not seen any indication that they are longer lasting. The 5000mAh does not refer to the amount of charge. It refers more to how many times they can discharge and be recharged, just for you to know.

Size is out of specifications.
These are slightly oversized and may cause fitment issues in some devices. Additionally 3000mah seems more accurate than the advertised 5000mah.

One Battery will not Charge
Package came with charger and 2 batteries. One battery will not charge. I tried to charge it in both slots on the charger but it stays red, never turns green. Other battery seems to be ok.

Long lasting batteries
Used in a radio for flying RC airplanes, and such. I'm surprised at how long they can last without needing a charge
