They fall out easily...

Great idea, bad execution.  The pockets fall out of the door a LOT.  My dog is very active, but still...the little tabs that you fit in between the window and the door should be longer or something.  Disappointed.

They fall off way too easily.  It's worth spending  a few extra bucks to get the Symplicity ones that actually stay on.  YRMV, but we won't be using these again.

I bought these about 2 years ago.  I hear much better with them but they fall out very easily and are so small they are hard to find.  Consequently I lost the right one about a year ago and just lost the left this week.  They are comfortable and do work well but if lost that is $900 down the drain!

I recently went up to a 00g and had only tapers to wear. I ordered these for the price and quantity, thinking I'd have many options. Sadly, most of them fall out of my ears whenever I would change my shirt, sleep, etc. I stopped wearing them bc of the hassle of trying to find where my gauge rolled off to each day.

My husband lives in these. Just needs to keep an eye on the pockets. Things fall out easily.

I like them but the plastic fittings pop off.  I have tried the various sizes but when running they still fall out.

I really liked them at first, they are pretty to look at and the balls are a decent size. However, they don't screw on very tight and fall off easily. I lost every ball within two weeks. I wouldn't buy them again.

These buds keep falling out. Seriously, who can wear them? Especially at the gym. Very disappointed. I'm not using them much anymore.

They are cute but don't have a complete ring, so they fall off the rod easily. I'm looking at fixing this as its a major annoyance that I can't scoot the curtain back without 2-3 coming off the rod.

No matter how tight we make these they do not stay on the door for more than a week or so at a time.  They slip very easily, much more than plastic clips we've used in the past.

I love the look of these socks but the grips fall off so easily.

If you're thinking about using these for anything other than sitting in a stationary position - keep looking. I picked these up for running but as soon as I started jogging they fall out. Even if I push them back in my ears a little as soon as I move my head to either side they fall out. Other than the fitment issue they seem ok.

They fit the Badger Anthem, but feel like they could come loose very easily. They do what they should but I'm not 100% sold on plastic, they to stain and don't come entirely clean. They are probably going to be returned.

The tails fall off of these really easily, which maybe is a choking hazard? I don't know - we pulled them off though, just in case. Also lots of fuzz from these, at least initially. That all said - my cat LOVES them.

I purchased 2 and within 1 week I lost both because they fell out. When inserting them into the port, they did not feel loose.

These started out ok, but fell off within a few days.

They sound awesome, but speakers easily come off and get lost somewhere. I've used them for 3 days (they fell off 5 or 6 times in that time) and on the 4th day lost them completely.
