Might be user error, but I have having a heck of a time getting this sighted in on my Mossberg 702 Plinkster.

So far there software errors out and there is no way to contact them.  Even there contact software errors out. So I cannot use them. No way to reach them.

I think I may have a defective unit.  After some good, quality time with the install I cannot get the LED screen to illuminate and function properly.  Overall the installation is relatively easy and the deadbolt portion works just fine.  The wire connection between the front and back might be the culprit for a faulty screen.  Looks like I will have to return this and maybe give another one a try.  I'll give Kwikset a chance to return my email and see if this is in fact a dud. It's a new product and this stuff happens, so I'm not going to give a poor star rating.  Hopefully Kwikset can help resolve this.

I guess there must've been some copyright issue or something.

I'm giving this 3 out of 5 because I'm partially convinced this is a user issue, not a component issue.

I've gotten this screen to power up, but I cannot for the life of me get it to display anything. Granted, I'm not a programmer at all, so I'm still learning. Like I said, it's probably something simple I'm missing, but right now I'm banging my head against the wall!

As others have successfully gotten this to work, I'm giving it the benefit of the doubt and buying a "Python for Dummies" book....

Occasionally I'll have inconsistent unusual behaviour from my devices that are connected to it.

I think It could be that since there is no power amp, there may not be enough power getting to all your devices, but I'm not sure.

I just discovered another problem I'm having.  I already wrote an opinion and could not determine how to send the message.  All I saw was clear next to the stars.  A problem I'm having is having to learn to adjust to inconsistencies such as pushing the power button and sometimes being asked if I want to turn off the power and the power going off right after pushing the button.  Also, I just turned the power on and I was asked if I wanted to turn off the power.  I like having access to the internet with this tablet.  I won't throw it away.  Another problem I discovered I have is not knowing when or how to close a tab or article I'm reading.  I wanted to chat with a website and could not do it because I.was told I had too many tabs open.

I have had trouble installing this with my new Windows Vista system.  I'm not sure that this reflects a problem with the software, or something about my Vista setup.  I will update my review if/when I am able to install successfully.

An error message appeared on the screen and would not reset. Had to return this item. Had the same calculator before and it worked for a few years until the error message appeared and it would not reset. Unfortunate because I really like this adding machine. Manufacturer could not tell me the problem.

I threw away one because it was not loading properly and engaging in my device, but that may have been operator error.  The second one is working just fine.

I don't know yet how the error in the picture will affect the gps but I'm looking at other options at the time of writing. I will update this review once I find out.

So far, I have not been able to get this product to work as I expected. I am still testing, and hope that it is just something I am doing wrong versus the equipment not working correctly.

Not sure - having problems with my printer since I installed this - but it may not be the cartridge.

I had given this product a bad review and one star, but I am changing my response for two reasons:

1) I am still trying to get the digitizer to work, and I have found that the problem may have been caused by me and not by the product. I am still working with it and not completely sure if it will work, but it does appear that the fault was mine.

2) Their customer support have been very concerned with my review, and they have offered a replacement. I probably won't need to send it back, especially since I damaged the home button (not their fault), but the fact that they reached out to me and offered to replace the digitizer means that they are truly concerned about providing a quality product.

Its possible that I'm not using it properly but I have not been able to get this to work for me. Its not as easy as plug in, press start, and start talking. I'm giving it three stars though instead of two to factor in the possibility of user error.
