Clifford James Electronic Barking Guard Dog Security Intruder Alarm, Sensor Activated with External Speakers by Zennox

Will definitely buy again. Excellent value for the price. A great deterrent against thieves. Very realistic barking sound, plus the fact that the unit works on batteries as well as on mains power makes it truly portable for anywhere in the house. The portability means that the unit can also be used in vans and out-buildings which do not have mains power. I use quality alkaline batteries, and they last for quite a long time. Also, you know when you have a caller at the door whenever you are in the house.

I bought two of these at the same time, first thing I noticed was one was missing the power plug and instructions (a previous return maybe).I contacted the seller and they sent out a replacement plug very quickly.After very short use it was clear one was not functioning correctly, it would trigger by itself and then at times not trigger at all when something was in front of it, even at full sensitivity. I returned for refund no problem.After a few months the second one started to exhibit the same problems, additionally when it had been on for a long time it got stuck making a very quiet repeating noise and ignoring sensors, only stopped by turning off and on again.The seller explained this time I wasn't eligible for refund, only replacement, understandable but I don't have high hope for the replacement - will update here after it arrives.Assuming the devices had worked correctly I would have reviewed them 'good' - not great.The barking sound isn't convincing as others have mentioned and it would have been nice to have the alarm option alone without the barks first. Maximum volume isn't quite loud enough.I also noticed it interfered with wifi routers completely blocking my devices whilst it was on.UPDATE:I used the replacement device (my 3rd) whilst away for a week on holiday with fresh batteries, on returning the device was dead.I can only assume it was triggering itself again like my previous two devices and ran down the batteries.Honestly I've had enough of this thing now, I'll just take the £50 hit. I've spent more in batteries than is worth it.If you take the plunge I hope you have better luck than I did!

Purchased this mainly for the dog bark - which is ok for what it is. However I thought I would find a use for the ding dong bell and the Alarm feature as well. The first one I received would ring the bell and would bark but when I set it to Alarm it just barked again. The company sent me a returns label and, when they received it back, they sent me another one but said that they couldn't find anything wrong with the original. I tested the new one they had sent me and it was exactly the same as the first - it wouldn't sound the alarm. I called the company and even played the bell and the dog bark over the phone to them - then switched it to Alarm so that they could hear that it still just barked. They sent me another returns label and, after I had sent this second item back, they sent me a third one - again saying that they could find no fault with the one I had returned. This third arrived in a tatty old, second hand box and had obviously been used before. Once more only the bell and the dog bark worked. I phoned them again and demonstrated over the phone and they told me that they would send me another returns label and if I sent it back that they would refund my money. I pointed out that this saga had been going on for over a month, that I wanted the item mainly for the Dog Bark function, but that I resented paying full price for something that didn't work as it should. They guy told me that the last two had operated properly on return and that, apart from a refund, there was nothing else he could do. I said that I really needed one before I went on holiday and that I was going in the next few days and didn't have time now to get anything different. I said I was prepared to keep the faulty item if he gave me a part refund as only two of the three functions were working - he told me he could not do that and that I would have to return the item. After a further discussion he compromised and sent me a returns label for when I get back off holiday - when I will return the item for a full refund.Although the company have been helpful they can't seem to send me a working item and just keep saying that the ones I return are working ok - which they don't at my end (and it's not exactly rocket science to switch from one function to the other!) I will be returning this and getting my money back and then I shall look for something that actually does what it says it will.If I was you I would look for something else in the first place.

Product seems well made and works as it should. The slide switch has three sound settings; 1. bell, 2, barking dog, and 3, alarm. On my unit I also have a barking dog on setting 3, but I am not really concerned about that. What I am concerned about is the battery drain. I installed brand new Duracell batteries but 4 days later the unit started behaving eratically and then finally stopped working. I checked the battery voyages and found that the charge was 35% down, after just 4 days. The unit works fine on the mains adapter but I have no mains supply where I intend the unit to be installed. This is very disappointing as I had expected the batteries to last a few weeks, or at least as long as a couple of weeks away on holiday!

Delighted with this product! Really realistic sounds and with the sensitivity dial we have worked out what’s best for us, even had our Amazon delivery driver fooled! Really has given us peace of mind, as we were broken into whilst in bed this year, and we can certainly rely on thus to warn us. I have even posted a warning dogs sign! If there was any criticism it would be batteries only lasting about 5 days at present, but we do set it when we are in also, so extra useage. We are having an extra plug socket put in, so will run fine then from mains, otherwise really excellent device!
