I usually keep the car keys in the same place, but once I misplaced my keys and searched the whole day to find them. So decided to get this one and it really worked as described. After that I never really got a chance to use it other than testing to see it works :). It comes with four key fobs and a remote with a stand. Key fobs come with 2032 coin battery, but the remote does not come with standard AAA batteries.

It worked perfectly fine and sound is loud enough to heard from across the room. This one would definitely save time when we are searching for keys!!

 This is a review of the Esky wireless key finder. It's available from a few other sellers so shop around before buying.

The idea behind this product is that a receiver is attached to an item that may be misplaced (keys, mobile phone, purse, etc) and when it can't be found the corresponding button on the transmitter is pressed, causing the receiver to beep. You can then use the beep to find the missing item.

The key finder arrived simply packaged in a plastic bag. Contents:
• 4 x receivers, each with a different colour dot
• 1 x transmitter with stand
• 4 x CR2032 batteries
• 4 x keyring attachments and adhesive pads
• Manual

Each receiver takes a single CR2032 battery (provided) and the transmitter a pair of AAA batteries (not provided). The manual is quite brief but clearly writtern and it describes the use of the product well. It's really all common sense though so you shouldn't have any problems getting it up and running.

In use I found it to work very well. I initially thought the alert from the receivers was a little faint but when testing all over the house I found that not only did the receivers beep from pretty much everywhere but I could also hear them. The transmitter does have a built in LED light but it's not particularly bright.

I'm only using these with keys but the receivers can be attached to other items using the provided adhesive pads. Due to their size and relative chunkyness they're not ideal for smaller items or things like mobile phones, really. Of course with a product like this you need to be within relatively close proximity to the misplaced item - they're not going to tell you you left your wallet at work when you're at home!

Pros:
+ Simple setup
+ Good range - worked pretty much all throughout our house
+ Loud alerts

Cons:
- The receivers are quite chunky (the reason they're not a five star product)

I'm very happy with this set of key finders. They work very well and are a bargain at the current price of just under $25. Due to their size they're not ideal for certain objects (great for keys or for slipping in a purse, not great for mobile phones). Recommended.

So far, it has been very useful. I have a tendency to misplace just about everything I own and this helps me track my crap.

This was a gift for my father for Christmas. They work really well. Beeps loud enough to hear and flashes color too!

They were good I would recommend to anybody

Works fine. Alarm could be a little louder.

Would love it if the alert volume was louder and the discs a little smaller.

Perfect for someone who always lose stuff

Very helpful whenever I use my keys or remote. This is a very simple device where there are 4 keychains and a remote. Each keychain is color coded according to the color on the remote and when you press that button, the keychain rings. The remote comes with a stand and has a handy LED flashlight.

These are very easy to use and get working. All you have to do is the install the included batteries and then you are good to go. They have a high pitched good volume sound so you should be able to find it with ease.

This product would be useful to not only people who lose their keys but for anyone because at one point, everyone loses their keys and it always takes forever to find. You also don't have to limit this to only keys, you could put this on a remote, or anything else that is something that is often misplaced.

Overall, I think this is a very useful and great product. It does what it is made to do and a I have not received any problems and I do not expect to receive any either. This is a great buy and I recommend to everyone.

I was supplied a sample for test and evaluation, and I promised that my review is fair and honest.

I love this key finder.  Unlike the reviewer who says they admit that they never lose anything, I admit that I always lose my keys.  I have only had this key finder for a few weeks and I have already used it twice to find my keys.

The packaging was easy to open and the fobs were easy to set up.  It came with four batteries which I had to put into each fob but they were easy to install.  Fortunately I had four AA batteries for the transmitter because they were not included with the device.  Again, they were easy to install.  After installing the batteries, I placed the fobs all over the house, including in my wife's purse and in a drawer.  They were all easy to find and the sound was loud enough that I could year the ones in the purse and drawer even from other rooms.

It would be nice if the fobs were a little smaller but they are not bad at all.  The only ones I have found that were smaller did not have replaceable batteries.  I would rather have the larger ones and be able to replace the batteries instead of having to replace them every year or so.  They are small enough that I have two of them on my key ring.  The reason being that I have a removable section with the key for my golf cart and I want to be able to track both rings, even when separated.

I would like to be able to track devices from my Android phone but the locators that do that are much more expensive.  For the money, you can't go wrong with these.
