Didn't Work....Except on us
928174
We purchased this spray as we have been having problems with our 35lb. Shiba Inu and our 25lb Basenji getting into awful, bloody fights in which one of us usually ends up with a nasty bite while breaking them up. I was hoping this would safely break them up if they fought again. Wrong. They got in a fight yesterday and I emptied the spray can on them, directly in their faces, and it did not slow them down. The fumes however made it hard for my boyfriend and I to breath while we tried to separate the dogs. During the fight, the bright orange spray was then rubbed into the floor. To top it off, we then had to bathe the dogs which ended in the spray residue getting "shaken" all over us during the baths. It was a mess. My eyes were on fire, I couldn't breath and my skin was on fire for several hours and I have a white dog that is stained orange. Overall, a horrific experience that I will not repeat.

We tried several different digital optical cables - but we could not get this device to work at all! We are now purchasing a more expensive solution to see if we can get it to work. Thankfully it looks like Amazon is taking it back without any cost to us. Thank you Amazon for a good return policy.

I ordered this product and it did not work for us.  I tried it on multiple units and figured that I would try something different.  Could have been user error which is why I did not give it less than three stars.

Pretty simple. It didn't work, had to return it.

Not sure if it was our wifi connection or the camera itself , but we could not get it to work with our phones.  We downloaded the app and got it all set up, but it would not track and the picture was grainy and didn't follow the commands when trying to rotate it.  We sent it back and are looking at other  options.  We have since upgraded our router, so there is a possibility that was part of the problem, but doubt it.  I will update this review if we find one that works better.

Despite the reviews, I thought I'd give this a try.  Unfortunately, it just didn't work.  My husband, a retired mfg engineer, did everything he could to get it to work.  He called the customer service dept. and they sent him out a new one (great customer service - 5 stars), but the new one didn't work much better than the old one.  We returned both.  At the cost of blades, we really wanted this to work.  Hopefully we can find something that does.  The search continues......

We were so excited to get Mr Robot! But sadly, Mr Robot did not work at all. :( My little boy was very sad. We had no problems returning him and getting a refund! Yea! Maybe one day we will get another Mr Robot that works. We must have just wound up with a lemon this time around. C'est la vie.

I'm sorry to have to report that the unit I got just did not work. Had a few friends try to get it to, no success.
No problems with the return.

Diligently tried it with three different devices, but this transmitter/receiver did not work. All lights were on, every indication that it *would* work, but it didn't. Had to return it assuming it was defective. I was really hoping.... Not sure if it was just bad luck of the draw since others indicate theirs did work fine.
Also, please note when buying this product that instructions state that device and transmitter/receiver need to be within a short distance from each other (I forget, but it was just a few inches), for it to work properly. So, if you are hoping for a *remote* bluethooth type of listening experience, this transmitter may not be the best choice.

Whe we received it .....it did not work.  it took a long time to finally get a RMA# to send it back which they paid for...so cant say much otherwise

There is no worse review than saying, "hey I bought this and it doesn't work." I'm so angry.  I followed every guide and had friends and my husband try.  No dice.

Couldn't really get it to work like it said.  Probably our fault even though we did look at the Utube video.  We sent it back.

I bought this despite the reviews with hope, since there are no other such options on the market. Great idea if it worked. Very disappointed.

The sensor seemed to work, but the plug in unit never made a sound or turned the light on. You switch it to manual and then the light would come on...??.. I changed the frequency.. got one beep out of it.

I returned it and got a new one, same thing. Returning that one tom. I also noticed there were only four and all looked like they had been returned. The one I exchanged for had batteries from previous owner. Might add most Home Depot's only appear to have about 4 in stock.. not so popular??
