The bag seems to be well enough built and the design is good. Attached it easily to my handlebar, and it's convenient to snap in and out of the holder. My only complaint about the bag itself is that the clear plastic viewing window seemed not quite clean when I received it -- there's a little bit of a film or smudges hindering the transparency, and it seems to be mostly on the inside. I tried to wipe it off with a damp paper towel, and it did get little bit better, but it's difficult to access the interior well enough for a good cleaning. I'm also not quite certain whether all of the smudge/film can be removed or not.

My Motorola Droid RAZR Maxx fits snugly in the bag. It's nice to not have it flopping around in there, but takes a few extra seconds to slide in and out, due to the snug fit. Don't try the bag with a bigger phone than that.

The main problems I've encountered when using the bag are not the fault of the bag. My phone display is simply not bright enough to use in direct sun, especially when I can only afford to glance at it for a fraction of a second before I need to return my eyes to the trail ahead. You can use the touch screen through the bag's window, if you can see what your're doing. And then, of course, there's the phone battery life issue when the GPS is enabled, the screen is running full time at 100% brightness, and the cell network signal is weak or intermittent. My battery lasts through most rides, but on one especially long ride even the unusually large battery of the RAZR Maxx didn't make it.

Works just as advertised.

It's a bit irritating the way you have to burp the air out of it ( a pin valve would be nice ) so you end up with a phone in a balloon if you don't carefully press the air out before using.

The touch portion works fine, the glare is no worse than the screen itself, and the mount to the bike is very secure. I put my HTC EVOG into it, it was tight but did the job.

It's a bit hard to remove if you have large hands like I do, and you can easily snap off the connector on the bike if your not careful. The need a bit more clearance between the case and the mount in my opinion.

After looking at and trying all the other mounts this one was the best bang for the buck for an Android generic phone in my opinion.

It's a very well made product, solid materials. The clear panel easily permits the screen to sense touch (unlike some others I've tried). The only gripe I have with it is that there is no way for me to get my earphones plugged in without leaving it open and even then it isn't that convenient because of the way the bag must be rolled before closing. So I guess I have to invest in a set of bluetooth headphones now in order to really get this working right but I was intending to do that anyways! It's a tradeoff I'm fine making since I wanted something really waterproof that could fit a variety of phones and still had a design that was high quality and well made.

I also own the iPhone case from Top Peak and bought this when I switched to an Android phone. This is not nearly as good a their iphone case since its a bag for many different size devices. The bag is a snug fit but it shakes/vibrates a lot while I ride because its not a hard case. The phone is also behind a plastic film which adds more glare. The sides are thick which makes hitting the power button (an important button) quite hard to press. Volume buttons are almost impossible to press as well.

This is a well-built product, but don't expect greatness from it as its a one-size-fits-all bag.

If you looking for a bag for Moto X, look no further ... this is the one. It's fit pretty well. Not tight fit though. The plastic cover allow you to still access the phone. This bag build in such a way that there will be nothing get to your phone ... no water, rains, dust etc. That also mean no way to get the ear plug in there too. However, bluetooth is work! ... you can pair wirelessly!

It's come with a bike mount which allow you to mount the phone both vertical and horizontal. You do NOT need to buy an extra bike mount!!! (that another 20-30 bugs more) ... I wish I known this before I order mine.

Outstanding piece of equipment as one has come to expect from topeak - with extra mounts one bag gets moved from bike to bike rather than having to purchase several complete units -
If the back were stiffened up some it would be about perfect
Have always hoped Topeak would make additional mounts to go on a belt or on a backpack strap

Shock and vibration concern, not only on this particular bag, but on all bike phone cases - I have owned the dry bag for over a year: it is well designed and built: no problems (--> 4 stars).
I noticed a bike buddy wearing the phone at his shoulder, as runners do it. This made me think about all the vibrations and shocks my phone is exposed to, when mounted to the handle bar. I decided to give the dry bag to my dad, as he rides on smooth trails / surfaces, and get my myself a bag as runners wear them.

Fit my Samsung Galaxy Note 4 perfectly! Rolls and "ziplock" seals for full waterproofing ... Use it for hiking, amusement park trips, and on my foldable bike for commuting!

Good fit on the phone (samsung A3 ) . Well protected from elements. Touch screen works very well through the cover. Only Down side is the visibility of screen in sunny weather ,it is very hard to see .but it is a well made case with a good bike attachment bracket.
