Excellent value
Excellent replacement battery, they come charged, they hold a charge every bit as long as the original batteries and they charge quickly. Awesome value compared to competitor replacement batteries. I highly recommend. Side note, if you purchased these batteries and they didn't work out for you, perhaps your charger is the problem.

More power but just a bit shorter worktime
I liked that it fit the tools. I liked the extra power for the chainsaw. It does not have a batter charge indicator like worx but it is just fine for the good price. I plan to order two more soon for my chainsaw which I use a lot and need the extra batteries.

Rechargeable batteries
These work well in my Worx blowers and hold the charge but never long enough!

Awful
These batteries are absolutely worthless. I finally had a chance to try them. Fully charged, they will not run anything for even 30 seconds. I have tried my Worx mower, weedwacker, leaf blower, and hedge trimmer. NONE will work with these. Unfortunately, due to a health issue, I have been unable to try them until now and have missed the return window. I want my money back!

Batteries for Worx weedeater.
Product is great. Charge last longer than original batteries. Great value paid $28 for two batteries and competitor sells one battery for the price.

You get 1/2 of what you pay for!
One of the batteries was DOA, and wouldn't hold a charge, but the second one was great. Much longer life than OEM version, when you run blower on low. High speed only lasts seconds. For the yard work we do, this works out fine. Company was very quick to offer a complete refund for the dead battery, since they were out of stock on replacements (and Amazon automatically refunded the sales tax). Refund was in my Amazon account within 2 days of contacting the vendor, Elefly!

A+
I have an older craftsman grass trimmer and hadn’t used it in a few years. When I went to get a battery for it seems like the trimmer is now “obsolete” so then the long tracking of what battery replacement. So I took a chance on these and so far this whole summer they have worked great. Can’t say that for the dewalt replacement batteries I’ve bought for blower. They didn’t even last a season. Probably why I’m so excited about these.
