Nicely designed - but not usable on my Galaxy S3 - the people on the other end heard their voice echoing during conversations.

This was just what I needed, except: it's not compatible with unlocked Samsung phones, so don't buy it if it's your case. It took me days of wasted time and interaction with all manners of samsung support, on line, and on the phone, to find this out. Basically, the Samsung Gear app required to connect the device to the phone cannot be downloaded on an unlocked phone.

You can still use the unit, however the functionality is greatly reduced because it will not interact the the S health app so you won't be able to track the info, update gear, download clock faces, get notifications from your phone, etc.

CLARIFICATION: If you have a Samsung Galaxy J7, Model SM-J700M, Gear fit2 will not work with it. This phone is an unlocked, international version that works in North America (with T-Mobile, in my case) but is NOT SUPPORTED by Samsung. In fact, if you try to search for that model number on the Samsung site, you will not find it on their database! I finally found a Samsung technician at Best Buy that confirmed that the phone is not supported and cannot be updated.

It's not a stretch to think that other unlocked Samsung phones will not be compatible. Your best bet is to find a knowledgeable Samsung technician to verify compatibility with your model. It took me 3 different technicians!

I just received my Tune Belt armband "for Samsung Galaxy S III and more" and my first impressions are that it isn't perfect, but should do the job.

My biggest complaint is that the headphone jack cutouts just do not match the phone it's supposedly made for!  There are three holes on top, presumably to line up with three different headphone jack placements.  Sounds good in theory, but considering the product title uses the name Samsung Galaxy S III you would think one of the holes matched the jack on the phone.  Well, not so much.  The one on the left comes closest, but without pulling the stretchable, flexible top part to the right a good quarter inch, there's no place for the headphone cord.  I get that this product is intended to be for more than just one model of phone, but if you are going to use a specific phone in the product title, it needs to match that model without having to force it.  I suspect this rather cheap-feeling product won't be very durable with it being stretched to accommodate the cord on a regular basis.

Other than that, the phone is pleasantly easy to get in and out, mine even fit in with the case still on.  I have a simple snap-on back case though, so anything with much thickness or full protection will NOT fit in the armband.  If anything, the phone is actually a bit loose in there without the case on the back, but it doesn't appear to be loose enough that it will fall out.

Lastly, I don't have large arms at all but it is a tight fit...if my arm were much bigger it wouldn't fit well at all.

Overall, it's decent for the price, but I don't expect much in terms of durability, and if you expect it to fit your Galaxy S III perfectly, this may not be the right product for you.

I ordered this item (waterproof mobile mount) specifically to fit my Android phone inside and mount on my motorcycle. The description says the maximal HxWxL. Therefore, I thoroughly measured my phone to ensure that it is smaller than the maximum. It was smaller, and so I ordered the product.
There is a design flaw, that does not allow Android phones (and possibly other devices) to work properly with the case. Being that the case's title and description make it clear that it is for smartphones (and Android phones and iPhones are practically the only popular smartphones), I assumed that the design takes millions of Android phones into consideration. All Android phones come have a touch sensitive "soft-keys" set on the bottom of their front face (under the touchscreen) in which the critical keys are placed (home, back, settings, search). These soft-keys are not accessible when in the case as the lip of the case covers it.
Also, Android phones all have lock/unlock keys which are located on the top of the phone. The lip of the case also covers that button, and does not allow the depression of the button.
The case otherwise seems sturdy and water-resistant as it was advertised. It could possible work with other devices like GPS systems which have no buttons.
Being that the fault is clearly not mine, I asked thrice for a shipping label to send the package back to the UK, where the seller is located. I was denied twice and the last request was ignored.

I have the Samsung Galaxy S6, and a variety of cases. This device will not work if I use any of the cases I currently own [I'm still looking for one that does accommodate this]. Also, the little case for the card reader is nice, but it's the kind of rubber that attracts and retains hair, lint, and dust. You'll find yourself forever attempting to clean it.

After reading some of the reviews here, I decided that this little dock would be great for my SG2, especially because it would let me dock my phone without removing the case.

Well, I was WRONG. This might work with some cases but NOT WITH ALL OF THEM. If your case is thicker than 1.5mm (to be specific, eg: D3O sold by Tmobile) this WON'T work.

So, please, don't be deceived by the "You can dock your phone without removing the case" statement from other reviews.

PROS:
- Cheaper than the Samsung Dock
- Nice looking
- Easy to assemble
- Lightning fast shipping

CONS:
- Half the price but also half the quality compared to the one by Samsung.
- Phone with cases which are 1.5mm or thicke cannot be used with this dock
- SGS2 with large screens seem to be a bit unstable.

Just what I was looking for and great concept, but execution needs tweaking for Samsung Galaxy 2.  The phone fits in the enclosure sans case, but it is alittle difficult to use the four capacitive buttons as the seam between the clear window and neoprene covers it.  It is abit annoying because I have to loosen the velcro that holds the phone in to move it up slightly so that I can manipulate the buttons and then refasten it.  Fortunately, there is a "ribbon" that prevents the phone from slipping out if the velco is not closed completely.  Still, it is a well made product that fits comfortably around the waist.  Perhaps it fits other phones better, but it is a functional sport belt for the Galaxy 2.  I now wonder if I should have gotten the larger version that fits an otterbox case as ideally, I would prefer not to have to take my case off. Perhaps I will invest in that one at some point in the future.

DOES NOT WORK FOR GALAXY s3. Worked fine for other android models though

Works great... but will not fit if you have a case (and who wouldn't) , unless you remove it.  Poor design choice there.

I have a Galaxy S3 Mini but this case did not fit the phone well.  I did not return the case because I am living outside of the USA and the return postage would have exceeded the cost of the item.  I can say that the case is well constructed and would have received 4 or 5 stars from me if it was correctly sized to my phone.  (In fairness, I also purchased the phone outside of the USA, and it is possible that the international version of the phone is not the same as the USA version.)

After weeks of use my Galaxy S3 seems to be too heavy for the device.  It's a great idea but my phone ends up flipping upside down.  There must be a way I can secure the phone to stay upright.  Any suggestions?

This review pertains to the Note 3 case only - the first time I ordered this case was almost a year ago. I wanted to have the ability to stand my phone up and based on the reviews I thought this one would fit the bill. The stand broke recently and I reordered the same case - when it arrived, I noticed the design had changed significantly. The original case had a slightly curved back to it while this one was thicker and totally flat. The new design made the phone feel more substantial but still comfortable at the same time. The disappointment came when I tried to use the stand feature: it barely holds itself upright in landscape mode! It seems like the balance is completely off for a Note 3; any slight bump will cause the phone to tip over. You can forget about having the phone plugged in while using it landscape too - it won't stand up at all!

If you're looking for a case for your Note 3 for protection, this wouldn't be my first choice either. The top and bottom of the phone is exposed so it's not a fully surrounded case. I was willing to forego this because of the stand feature but considering the stand doesn't work either, it makes the case useless for my purposes.

If the manufacturer stayed with the older design, I would have no issue recommending this to any Note 3 owner looking for a stand case, but the redesign is a no-go in my book.

Otherwise promising unit, but not usable with a Samsung Galaxy S7. The resting shelf at the bottom of the cradle has a small opening that does not allow you to connect the USB charging cable to the phone or the earphone jack. Called the vendor to find out if it would replace the unit with another that has wider opening or legs. Vendor advised to just return the unit. Returned as unusable.

Unfortunately,  I didn't realize that s6 and s6 active were different so it is too large for my s6. It would have been otherwise,  exactly what I wanted.
