Not very helpful! No technical or how-to information. Only a few illustrations. More of a motivational guide. If you are looking for a construction guide buy Louche's "Design & Construction Guide" instead.

Does not work...
Does not have any instructions.

A new level of frustration has been reached....No written instructions as this seems to be the new norm... lhowever, I first hookup what I see...figured I could do this like I do most techie stuff, Just do it... but those damn walls are so unforgiving! So I had a younger generation stop by to try and help me take a picture of a small rock.  He was to take one (1) picture of rock and he had to leave.  He spent a little over an hour trying to take this picture. I spent around 2 hours to take one of the same rock.

I will take a look at website but if Im still in the return window I might just give up...unless I could get a written manual?  Theres got to be a better way

Still not sure about any benefits from this and the instructions are not very clear so cannot proffer high ratings!

This is a decent product. My electrical experience helped to achieve a professional install (or at least I think so), the biggest issue I can imagine in most cases is wiring/cable concealment.  THE BIG PROBLEM is the manual!!  I am 55, hold a Masters Degree in Nursing, a practicing NP, have  decades long electrical experience, and am fluent with all the current PC, tablet and Smartphone technology.  But I can't understand the dang manual.  This thing is written in choppy, poorly translated Chinese to English, does not describe the relationships between features and how they are supposed to work (such as motion detection, alarm tripping and email transmission).  Also doesn't define abbreviations and acronyms!  It's BAD.  I attempted to reach Customer Service.....there is none!  Got a short note from "somebody" telling me to read the manual! HAHA, really!  I Googled the manual and found a competitor's manual for similar equipment that was written in understandable English, that helped more than anything.

Returned because instructions were vague, did not function properly, and was too bulky!

No instructions and not convenient to work with.

Sucks!  No pics no written instructions....nothing explaining how to use.  Finally figured out correct placement/installation.  These do NOT work.  Major pieces of crap!

There is no manual or software shipped with the unit.  It only provides a link to the software and manual.  The 2 page PDF took almost 5 min to download and the software link is inaccessible.  The support link to contact someone doesn't work either.  What good is this unit without the software?  Worthless!

The package did not include any instructions what so ever on how to connect and assemble my cables to these plugs.  I now have parts and no idea how to make them work?  I hold a degree in Mechanical Engineering and I can promise you that the assembly of these plugs is not obvious!  Based on the sheer aggravation of this alone, I would not recommend these to anyone!

I just bought a new Kindle HDX. Since there was no manual that came with the Kindle, I immediately did a search on Amazon, hoping to find such an animal. That's how I wound up purchasing this book for 99 cents, along with several other simliarly-priced "complete guides" to the new HDs. Well...

There is no way I would consider this book to be "complete!" It's about as rudimentary as one could get. It's absolutely missing any coverage in depth about anything, especially concerning newer features. You will learn how to turn it on, charge it, and buy aps in the Amazon store, but not much else.

Bottom line: is it worth the price? If you're an absolute newbie and this is your first Kindle, then "perhaps" or "maybe, with some reservations." For me, who over the years has owned an original B&W Kindle reader, then a Kindle Fire when it first came out, and now the new Kindle Fire HDX, I needed something a lot more detailed and informative. As a final little gripe, I discovered some differences between menu directions in this book (meager as they were) and the menus I'm seeing on my new Kindle. Changes in the Kindle UI? -- or an already out-of-date book?

FYI, I couldn't see where I got 99 cents worth of knowledge out of this book, so I returned it to Amazon for a full refund. Caveat emptor!

In short, this is a troubleshooting guide compiled by someone who has no knowledge of J2EE. I think the text is copired from some technical forum or Blog...I am not seven ure how the manages to get published, but he has written similar books on many other topics, sold on Amazon. I think the author publishes his own books. Authors credentials are not mentioned anywhere in the book (just the name)....the book has no logical flow or content management. It is highly disorganized...actually after reading few pages you will even forget anything you know about XI....

I think this is a SCAM!!!

Not friendly at all.....If you know nothing about technology don't buy this. If you know a little about technology expect to feel like you know nothing....Tedious to setup! I haven't given up on it yet but there is only so much time I will spend on something that is supposed to make things easier.

Super confusing with very little instruction on how to use. Mine is sitting in its box. Unused. I'm sure it's a decent interface but I'll most likely never know

Might be helpful if you are really technically challenged.  Also useful to get an idea of what a ROKU does.  Basically re-copies the instructions.  Nothing very insightful.

No directions came with it.  I have no idea how to use it!

Came with no instructions -- as beginners, we're lost! Not much help from the supplier, and Zebco's website has little info for beginners.
