Good for the price, and you get a few so harder to lose them

These are good for the price, especially since it's a pack of 4 so of they dull or get lost there are more.
A bit flimsy, but there are four of them so not really an issue.

The work pretty well, and I've been happy with ease of cleaning, etc.  My only issue is the looseness of the rubber inserts, which leads me to believe that I'll eventually lose one or two.  For the price, though, I'd buy them again.

Pretty good, especially for the price.  Infact I bought 5 more just to have around in 2 cars.  The rubber support does come loose and can fall off, but once you figure out the best method of putting your phone in and out, it works well.

On the 2nd order I had 2 notes that my card was declined, when I added another - I got two orders.  Overall happy

Were at first less intuitive on how to wear them. Someone has them pictured to up "upside" down on their review and I tried that, but the wire started to become annoying. It would have been nice if it was labeled right/left. Once you figure that out, these are pretty good.

Because of the extra features, I was expecting a very noticible difference between these and my $12 Skullcandy ink'd 2 (I have an older version and a newer version of those and the older were slightly better.

Anyway, for the price these are pretty good. I might even buy them again over the Skullcandy because the construction does seem slightly higher quality (especially the cord/wiring) is probably worth the extra 8 bucks.

Sound wise, I wasn't floored in the differences, but still above average quality.

As spare lights you can throw in a drawer to use in a pinch they're great. I use them for walking the dog and around the house when I need a little extra light. As other reviewers have reported, the durability is questionable. Two months after buying them, one has died, but at a few bucks apiece it's still a good deal. I wouldn't use them for anything where your life would depend on it - for that kind of application get a Maglite or Surefire.

Good for the price, but didn't last too long.

These look and work fine, considering the price.  They're not the smoothest operation, nor are they the prettiest finish.  But for the price, they can't be beat.  They'd get four stars, but I ordered two, and one of them didn't move freely and was scratched.  It was returned without a problem, and I got another that was fine.

I swam for over 4 years without getting swimmer's ear, but have getting some bad cases of it the last few months, so I opted to try these at the add-on price. For the price point, it was a steal. Suffice to say, no more swimmer's ear! However, these are a little tricky to put on, so sometimes water still leaks in, but not nearly as much as swimming without them. Wish they had smaller sizes available for people with small ears such as myself.

All in all, they served the purpose that I bought them for. Now let's see how long they last.

I don't know why these things fall off, but they do occasionally.  Might be a quirk with my camera case.  Anyway, having some spares around is definitely useful.

For the price, these are hard to beat.  Everything worked as advertised, and none of the three that I bought broke after a week's worth of kid to teenage use.  My only other snorkel set is called the Reef Tourer by Tusa, which I don't even know if they make anymore.  If I had paid the same price (Tusa's were $60) then these would have gotten a 3 or 4 star rating, but I'm adding 1 or 2 stars for the stellar price.  They work fine, but they aren't top of the line.  The fins are hard plastic inserts in rubber vs all rubber construction.  The corrugated piece of snorkel tube actually makes it a little floppy, so it took some finesse while snorkeling to get it working right.  Not constant, but consistent adjustments while in use.  Other than that, no issues, leaks or even minor problems.

They don't hold as well as I would have liked, but they don't need to be replaced as frequent as others I have tried.

They work.  Period.  But you need more than just the four that come in one pack.  They can get pricey at that rate.

I don't know you, but I tend to loose things, especially clip on sun glasses.  These are relatively inexpensive, much, much less then most name brands and they work just as well.  If you loose these, don't worry--just go to Amazon and by another pair for a couple of dollars.

These are great, long and durable.  One problem is occasionally they do get lose.  I have one where the connector gotten lose over a year of use, out of 4 that I have gotten.  I'm considering getting more though.

These are GREAT for the value, they are super cheap, but they do not last long.  If you're not like me and don't need 20 spare batteries for intense amounts of shooting, you're better off buying an official battery.  But considering you can get like 10 of these batteries for the price of one Canon official, it's worth it for me.

These are fine, but nothing special. One or two had the tip fall off, and another had the clip fall out, but most have held up well. I was unable to replace them since  they no longer fit.  They are very lightweight, which gives a bit of a flimsy feel. It may just be my personal preference, but I end up reaching for my heavier styluses over and over and fine them easier and more comfortable to use. These are basically an emergency backup that I only use when I have given up looking for my other ones.

The tip does work well and makes contact with the screen every time.

These are ok for the price but you sometimes have to move them around a bit to make a good connection.
