Worked great for a while

Worked great for a while, then the hook broke.  The ring that attaches to the battery wore a groove through the hook.  I went to a local craft store and bought a package of new hooks from the jewelry section.

Looked and worked great, for a while anyway. Now it doesn't work anymore. Does not turn on.

Worked great for the first few months, great sound and range but after a while it would stop connecting to my phone and computer. Then it would say its connected but not play any sound as well as disconnecting itself.

Worked great for a few months, then the housing end that plugs into the Mac started to come apart. It's still usable, but have to keep pushing the housing back on to the connector to not expose the wires.

Worked great for a while, easy to use, great prossure and nice nozzle. Then would not retract at all, found the smll timing belt that drives the hose latterally so it spreads accross the reel came off and the hose stopped the retracting. I tryed to get the belt back on with no success so took it apart,the spring inside let loose so pitched the whole unit. Will try one more and hope for the best.

Using with an iPhone 6S.  Worked great for a while.  Hardly used it.  Kept it in a padded bag.  Very well taken care of.  It decided not to work one day.  It wigs out like a short in the board or something.

Worked great for a long time. Got lots of charges out of it. But, it just recently broke on me, had it only about a year.

Worked great for about a year. It was very loud but I had it in a large room behind a couch so it seemed like white noise once somewhat muffled. After about a year of use it got very very loud and then one day stopped working all together. I loved it while it worked and have bought a replacement - it's cheap enough that I don't mind replacing it.

Title says it all.  It worked great for a while but then all of a sudden stopped working.  Quality probably isn't there.

Worked great while it lasted, but several months after purchase, stopped working altogether.

Worked great for a few months and then didn't. I'd have to click it a few times to get it to engage, and eventually it stopped working completely. I'll probably attempt a repair at some point, but for now it's sitting in a box.

worked great for awhile, but then as with most of these choppers, gets broken after about a year or less use. If you come to it with the realization that you will prolly have to replace after a year, its an amazing time saver and we will probably buy another one.

I use one of these in my small fish pond outside. It worked great for a few months then suddenly stopped working and was making a lot of noise. After messing around with it for quite a while I determined the impeller was not working properly, it was not making proper contact with the magnetic shaft. The little groves were worn off that pushes it around. Mine was able to pull completely apart, seperating the magnetic part from the upper impeller blade assembly. I superglued the two parts together and it is working great again. I just took out the center shaft upon which it all spins on as to not glue that part accidentally.

Worked great for a year or so.  Recently started malfunctioning; double clicking instead of a single click and other anomalies.  Tested another Logitech(M310) mouse I had laying around and did not notice the strange behavior as noticed with the M705.

Worked great while it worked. Did not last very long. I suppose that is why it is priced cheaply. I have tried many brands. this is one of two I have had an issue with.

Worked great for a while, but now it only punches 2 of the 3 holes.  I now use it as a paper weight.  : (
