Worked, but not for as long as I wanted...

Bought it about five to six months ago. Worked for fine for that amount of time. Now it doesn't work. It makes a strange noise, and makes a VERY bad smell. Don't know much about vaccums so I don't know what the problem is, but I expected a vaccum that costs this much to last much longer...

Fits fine - works for a while - then breaks. Yearning for a stronger one.

Worked fine for a little while, then lost two pins. Kind of a throwaway tool, but worth the $7 to get me by. I guess.

Works well for awhile, but it's not something you can count on long term. Mine lasted roughly 7 months before "biting the dust." So, keep that in mind when pricing it against it against their competitors,.

It worked for a few months of daily use, and then it stopped working.
I was reading other comments in here, and someone had stated the internal fuse flew out, and I cannot access it.
I give it a three because the on/off switch is awesome for my dashcam.
But, longevity wise, it did not last very long.

Cool gadget, however, it seems it may not last long. That's why I got two.

When this thing worked, it was awesome. But after about two weeks for one and a month for the other, no dice. Just didn't work anymore. Sometimes I was able to get them to reconnect by removing and re-adding it, or by hitting the button on the inside. But it really proved to be a subpar product.

worked good at first, loved the longer length, but didn't take long before they stopped working

I bought this mid-January, and it died on April 1st for no reason that I can fathom... It did the job during those few months, but I was hoping it had a bit more longevity in it.

Did what it is supposed to do.  Did not last nine months with moderate use.

Pros: Works fine (for a while)

Cons: After about five months mine stopped charging unless the cable was bent a certain way.

-Overall I liked it, just a shame it didn't last as long as I hoped.

Works as advertised, but after several uses it doesn't seem to charge as long.

It worked, but not the highest durability. Chord coming loose at adapter areas. Needed electrical tape not long after. Still works, but baby it for it to last longer, or expect simple tears.

Works well, wish they lasted a bit longer though. I might try another company next go around to see how they match up.

It worked maybe once or twice before it just stopped.  The build quality is actually pretty low, so I wasn't entirely surprised when it stopped.

Worked great at first, but a few months later it's not working anymore
