I bought this for the 11 hours of service. It is great for listening to audio books. It comes with different size ear pieces to ensure a comfortable fit. I bought this second M70 as a back up.

I've worked in the computer industry most of my adult life. One of the more common things customers ask me o do is transfer data from an old hard drive or computer to a new one. In the shop I can upload everything to the network, when on site I use a portable drive to copy everything over. Devices like this allow me to take the hard drive out of an old dead computer plug it in to a new one saving valuable time.

What many people don't realize is that shops charge for the time it takes to do a task not the time the tech spends on it. It may take two hours to transfer your data but the tech is only working on it for a few minutes. Most of the time the transfer is running on it's own. Put bluntly the tech may be billing several people for the same block of time. The average tech is expected to bill more than eight hours in an eight hour shift. During the average shift I normally would bill between 15 and twenty hours. Remember you are paying for the time it takes the computer, a set amount of time, or the time it takes the tech which ever is greatest. Sadly the tech working for a business gets paid for the hours they work NOT the hours they bill.

Anyone with a little knowledge can use this device for their own data transfer and save a load of money. I keep at least one of these on hand wherever I go just in case. I bought this one to replace an older unit that quit on me.

Changing my review, as it just died, 11 months since purchase.

So far so good.  I had one caller that would call 3 times in 15 min. and then went to 3 calls in 5 min every couple of days (that I noticed when home).  That has stopped and I am happy.  I am sure that as election times get closer the machine will be used a lot.  Thumbs up so far.

Very satisfied,  wish it lasted 12 hrs instead of 5. Packing said 8 hrs in use, not in standby.

Even though I have had it for just about 24 hours, I would have to give it five stars for the simplicity of its installation, as well as for the ease and quality of printing. Makes "hard wiring" redundant, replacing it effortlessly with a reliable wireless connection, given the fact that my router is on the third floor and this unit in the den at the basement level. Also, this is coming from a person who is arguably not as savvy in technology as many of the younger generation.

The contractor is later for like 3 hours but over all the service was good and very responsible too. Finished the work well and reliably.

so far the battery life has been outstanding. Tis replaces a dead battery so even an hour would have made me happy instead I'm getting 4 or more hours

My Husband purchased this battery and can't believe the life it has even as it is going through the initial calibration process.  When received the battery was at 58% and it took 18 hours of continuous operation before it got to 1% and the phone shut down.  He just finished the calibration process and will update this review as to the dependability and life of this battery. So far it is an A+++

So far it's been working fine. It appears to be well made and compact so easily portable. My only 'complaint' is that the instructions aren't clear on continuous running. They tell you how to set how many hours you want to run but it appears you can set the hours above 24 which allows it to run continuously. I was also impressed with the sellers sales support. I asked whether this unit may have been subject to the GREE recall, and they were very quick and forth right in responding. Also note this unit got good rating from Consumers Report.

Got 11 months out if this.  I was hoping it would last longer.

Bob had some charging issues and was sent back to the hospital for some repairs. Other issues were found by the repair team and fixed them. The service was excellent. The co. was very caring & generous. Everyone did a splendid job of taking care of Bob. he is back in service and performing the job he was designed to do. I am very well pleased with the service and performance of product.
Thank You so very much.

Works great so far with no bad sectors. But I checked the self-test logs and its 41k hours. Which is about 4 years. So I don't know how long this will last.
