Works well but short range. If I walk too far away from base it cuts off.  Also, the wires are starting to pop out of the protective covering near the plug. I'm worried it might break soon. For the price it works well. I'm hoping it last all season. I use it for drill team practice with 20 girls so they can hear me. Overall it has worked well with the exception of the range.

Works well so long as you have direct line of sight and the proper angle. Would prefer something with a wider range.

I like the design and 3-button feature, plus programming was very easy.  However, the effective range seems a bit limited as I have to be within about 50 feet of the door for it to function.  Perhaps the battery provided with the remote is a little old and its signal output is reduced ... when I get around to replacing, can update my review to reflect that is the problem.  Other than that, its all good.

When close it works well. However, any distance over 10 feet, or any wall or door that gets in the way makes the reception cut in and out. Disappointed by the range.

Works okay, much better within a short range than at distance. It won't pick up clearly past a few feet as some will. It wouldn't work with my living room Cortana set up whereas another brand did.

it a grate product, within a short distance about half a mile, but not to good at a longer distance. might work better if you have a straight line and no interference such as tall buildings

it works well.....
BUT
if you have a lot of traffic walking by your door...the battery ...needs to be charged...a bit too often

Works very well, clear sound.
Would be a higher rating but the range is very short. About 5 feet.
Thought maybe it was just the set I got, but I know 2 other people with the identical model and they have the same experience.

This works very well BUT I had to keep it at a close distance or the outside signal was lost.

It works ok if the distance is not too far away. There is a receiver between my computer and keyboard, the mouse and keyboard would not work, so I have to change location of receiver.

Slightly disappointed with the range. Maybe I purchased the incorrect model? Being Long Range, I was hoping it would cover both ends of my apartment, which are about 10-15metres from the mount point for this device. However, it only managed to cover one end quite well and not the other end, which the signals have to penetrate 3 rooms away to reach this 15 metres.
However, setup is extremely straightforward and easy.

Works ok, but the range is only 30ft  I use it for my office and the speaker must be very close to it, otherwise it loses the connection.
Just keep the speaker close by, or use it for other blue tooth devices.

I wish the range were a little bit more. It's pretty limited, and is worse with my BF's older mouse of the same model. Works well as long as signal is unobstructed and close enough. A challenge with my setup, or it'd probably get 5 stars. The color is sweet.

Works as advertised but the sounds isn't all that great. Bluetooth range only seems to be about 15-20 feet away from my device.

Good sound works well. Bluetooth signal is short. Have to be within 10 feet.

This works well for general location. However it will not assist in finding where the item is exactly within the building ie Under the sofa cushion, outside in the grass etc.

Works very well. Has no on/off switch. Does not have a strong radio signal so if you move your device into another room, your signal gets cut off. Other blue tooth devices seem to work better in this regard but I bought it so I can sit 15 feet away and not be attached to my stereo receiver with a cord to my computer or my smart phone. I say it works well and indeed does what I ask of it but you should know about the short radio signal.
