Question: Can I set up an invisible perimeter outside with this unit so my mother can still work in the garden but not wander off?
Document: I pressed the panic button, only to receive an SOS text message with the last place the device had been able to pick up a signal - my house, 30 minutes away from my current location. Trying to track via the web portal using my phone was frustrating since the website isn't very mobile friendly. Since I was testing and wearing the watch myself, this was no big deal. If I had received this text and my mother had been wearing the watch, it would have been very confusing and distressing.After a taking a day off from work - when I planned to visit my mom and get the device set up for her - returning the item, collecting and testing it, calling customer service several times, driving again to set the item up, and having the product on only two days (before my sister pried it off with a fork), I paid the early termination fee and gave up.The only thing more stressful than being a caregiver is trying to rely on products that don't work.
I was looking for something for my husband who has Lewy Body Dementia. He has not wandered, but I have read that 60% of people with dementia do wander. I love the fact that the watch can be locked onto his wrist so that he can't remove it. There is a special tool that you need to use that comes with the watch. I like the fact that if the alarm goes off showing that he has gone beyond the boundaries set, an email will be sent to you, alerting you. You then go to the website and enter your user name and password and will be able to see where your loved one is located.
First of all I have to say that I purchased the unit that I have for my mother from the Lok8u company. The cost was $150 from them and took 2 weeks to ship. Usually Amazon is much faster and I see the cost is cheaper. There are some glitches I think with the way the unit operates..It is not perfect and you do need to familiarize yourself throughly with how the unit operates. I found that printinging out the operating manual was helpful and doing some testing of the unit was also helpful.
When I say glitches.. I mean that it does false alarm from time to time, but if you have someone who wanders someone should be in the same building with them at all times anyways. You should not rely solely on this device to keep track of someone. Also I have noticed that sometimes when the base unit alarms it may take up to 10 minutes for the text alert to come through to the phone. We've had the device since Sept 2013 and there have been only two times my mother wandered and I was able to track her sucessfully..
If this is you, the product might work. I would caution you to allow time to set the device up; after a few calls to customer service (who are extremely helpful), I had to return the product to have the handset replaced.If you are a caregiver who does not live with your loved one, then your situation is similar to mine, and you might be out of luck with this product. I bought this product for my mom, who lives several hours away. My mom is in her 80s and likes to take walks.
I will make an update to this post once I get the device working. ***Update****I wish I could give this watch zero stars for poor craftsmanship! After getting a replacement base in the mail (two prongs were depressed to a point where it would not charge my watch), the watch itself still did not work even after the base now said it was charged. Nothing appeared on the display. After sending in my watch for diagnosis, I am now told I have to pay more money to have it replaced on top of my original purchase price (see email below).
Since she has some memory loss issues, we were looking for a simple device that would alert us to when she left the house and let us know where she was. This seemed like the perfect solution. The problem? It didn't work.Despite the T-mobile map showing that coverage was good to excellent, the product had a difficult time finding a signal (it took over an hour). Even when the device found a signal, any kind of actual location tracking that I tried to do by using the portal was inaccurate  (I stood outside for a while, inside, by windows - I tried everything).
Takes 2 hours to charge. I do not have a smart phone and thought about getting one but when I tried someone elses Iphone and tried to logged on to the website it did not work.. I have a lot of disatisfaction about the Lock8u website. Last weekend I tried to logged on and change the desiginated person to alert because I was not going to be home but another member of the family was. The site did not recognize my sign in password and I was unable to sign on at all. There is no one to answer a technical problem outside of their Monday -Friday buisness hours 8-5 pm eastern time.
It took 15 min or so to locate her. Previous to having the device she wandered and was gone for 12 hours untill the local sheriff finally located her. So for this reason even if the unit is not flawless, it does work. One nice thing is you can text the watch for a location, this works very well. The battery needs to be charged once a week if you don't have a bunch of wandering icidents..more often if you do. Every time they are out of range this will drain the battery.
I bought this FREEDOM watch in January 2014 for my 91yr old Dad who has Dementia. He is starting to &#8216;wander&#8217; and this watch has saved him a few times. Case in point- Yesterday he got away from my 83yr Mom and started walking down the street. She got in her car to follow him and parked a few cars in front of him to wait for him to walk by. He never did. There was a bus stop that my Dad past. Just by chance, a bus was there and he got on it.
Answer: You can set range from base station.  My mother can wander free in garden and fenced in yard without problems.  We don't rely on the unit alone and make sure she is accompanied by some one or in fenced/gated area.
