Husband loves his durable multi use case.  Great for working construction with the possibility of the phone dropping.  My teenaged son wants one just like it!  That's saying a lot.

Handy product, gives a great place for a cell phone. Comfortable and acceptable for daily business casual wear.

I am a home office worker that is on the phone a lot.  Tired of complaints that use of cell phone speaker resulted in poor, noisey communication.  Sound quality is very good, and others cannot tell I'm using a mic. Good, long cord.  Owned for 4 mos, and now part of my every day equipment.  If I had to buy again, I would probably get similar device with "behind the head" design (just a personal preference).  I would definitely recommend to anyone looking for a reliable hands-free solution.

Great - bought this to use while camping...so I would still have a phone in case I needed it.

Works really well with my cell phone. It's great that I can also use it to answer phone calls when they come in.

Great for your HTC Viva Touch if you work on the field as an engineer.

I picked up several of these cases for the Iphone 5C's that I support at work. The case is pretty bulky but that's a good thing I work with construction guys who get pissed and throw their phones all  the time. so far so good. No broken iphones have come back my way yet.

after a couple weeks users have reported problems with being able to hear it seems that there is a little fabric piece where the ear speaker is & people sound muffled to them on the construction site. I've since instructed my users to cut that piece out with a razor blade. I know this leads to more grime getting in there but usability is more important & I'm more concerned about the phone getting broken by being dropped which the case will continue to protect the phone just fine.

My grandfather works in construction, which means his phone is always at risk for extreme damage. He needs quick and easy access to his device while limiting the chance that something will fall onto it and break the screen. We have this to be the perfect solution because it offers a lot of protection with a design that is easy for him to carry around while at work. The phone clips onto the holster easily and it can be turned around for additional screen protection. He has dropped the phone and it did withstand the drop without a problem. The stand feature is also great for wasting time during a lunch break. If you want a Defender but care about your bank account, I would pick this one up.

This is an impressive phone with amazing build quality. It really does feel like it is ready for anything. If I were exploring the Temple of Doom with Indiana Jones, this is the phone I would take.

I am not a construction worker, work on a oil platform in the ocean or a truck driver but I work in I.T. and appreciate it's durability. The battery life is as advertised, awesome. At the end of the day, I still have 91% battery life. I am not even going to buy a charger for the car because I don't see when I will ever use it. Voice quality is unbelievable, the speaker phone is also impressive.

It does have some drawbacks though. It would have been the perfect device if it could get e-mail, even if it is basic. The belt clips also leave something to be desired, the two types that are out there have their flaws. The one Sonim makes doesn't secure the phone, the aftermarket one is close but it presses on the keys while it is in the clip.

I bought this phone so I can escape the smartphone mania. This does the job! I like the small company feel of Sonim and I hope they continue to make phones like this in the future.

Working on construction sites has many new safety guidelines to follow.  Since I liked wearing a vest to work in anyway, I ordered this.  It is awesome.  Lots of pockets to carry phones, pens, glasses and tools.  Also attachments to secure gloves or flashlights, and inside pockets that can carry an iPad mini or more safety gear to hand out to co-workers.  Love it.

Great fit with the LG - G6 phone. Seems to be one of the best phone cases for construction workers and rough handling. It does add quite a bit of size to your phone.

I got these for my husband for when he works outside in the yard.  He can answer his phone and hear everything clear.  He loves them

I bought one of these for a guy who works 1/2 a day a week as a gardener/groundskeeper so he could find MORE odd-jobs and so he could be contacted to run errands as needed.  For simplicity and ease of use, it's hard to beat.  The phone isn't the best and the service may not be perfect but FOR THE PRICE, it's just great!

This phone worked perfectly for my workplace, we needed a cordless phone for when I have to go out back in the warehouse.  I am in the office by myself most of the time and had no way to answer the phone before it rang to our answering service.
