They seem to last a little longer than the cheaper originals in my machine. This could also be due to me finally getting pressure dialed in for cutting right.

I bought them at a cheaper price so I'm not going to buy them again until the price goes back down because I can get them cheaper at the store. However they get four stars because they give you slightly more than 250 knowing that some of them are bound to die. They don't get 5 stars because they could be a little meatier, but I wouldn't call them small by any means. Overall I am happier with the purchase and can't wait for the price to drop several dollars so I can buy them again for about $9.

They work as well for short term storage.  No idea how long they will last as compared to the more expensive brands.

Good quality but it seems to last shorter than the A--90532 which is cheaper.

Time will tell if they last longer than the old ones, but I can say that they work very well.  If you need them don't worry about the quality, these are just fine.

these batteries last at least 5 times longer that the throwaway ones and in the long run they cost less.

These seem to last for only 30 days or less compared to the original that came with the pitcher. That last for over two months.

These do not seem to last very long.  They work for awhile, then they don't

This is the second order and I have had no problems and they last longer than the ones I was getting in the store locally.

No issues. They seem to be made of cheap material. Will be interesting to see how long they last.

These are still going after a year or more. If these things last more than that I think I got my moneys worth.

Just hope that this set which I purchased  awhile ago last longer the reason I had to order more is because the first set did not last they aren't used that much either only for a little while at night

These don't last noticeably longer than the 3aH batteries that came with my tools (although I haven't timed them), but I have put them through a couple dozen charges each and they still last as long as they did out of the box. I did have to modify a couple of my older tools to accept these batteries, though. But, they are all out of warranty, and it was just a very small tab near the groove where the battery slides in.

They are great! A little on the expensive side, but worth it to me.  I suspect that they will last much longer than what is found in the local store.

I seem to notice a slight increase in acceleration and gas mileage.  Time will tell if they will really last the lifetime of the car.

I love these, but they don't last as long as my Sears ones which look similar but are red.  I go through one every 2 years.

They're easy to install and they lasted much longer than the cartridges I bought at my local office store.
