Expandable for Wuloo Intercoms Wireless for Home 5280ft Range 10 Channel 3 Code (Only 1 Unit for Expandable The Original intercom System, CAN NOT Work Without Other Units)

I bought these so I cold talk with our son who lives down across the field in case he needs anything. They work very well

We've added a third unit for our bedroom upstairs. Units are easy to use and not very expensive to purchase. A text to the seller about our cat chewing off the antenna was quickly answer with an offer to replace the damaged unit.

Seems to work good

Ok, when I'm wrong, I'm wrong. I originally rated these 2 stars, because the audio was extremely distorted, and almost unintelligible. I have 5 units (this unit, plus a 4-pack bought separately). One in the basement garage/workshop, one in the basement storage room; the other 3 are upstairs - kitchen, office, garage. In other words, spread all over the house, up to 130' apart on two floors. This morning, I had a chance to play around with them. These are 10-channel units. I thought that was a privacy thing, and it might still be; I'm not sure. Anyhow, they come preset to channel 1. That's where I left them, and they had horrible sound quality. I set them all to channel 2, and VOILA! A world of difference. Now they work fine. Not hi-fi quality, by any means, but understandable from any unit to any other. YAY. My apologies to the manufacturer/vendor for the initial review.

This intercom set works very well except for 1 aspect. Because they are radios, there is a time lag between when you press the 'Talk' button, and when the other end begins to receive the voice transmission. If you do not press the 'Talk' button and wait for a second or 2, the front of the message send will be clipped. If this were not the case, I would have easily given 5 stars. I don't have a problem with the delay as I worked in the fire department for 33 years. I am very well acquainted with this Push to Talk delay. But it has been very difficult to get the persons on the other end to wait. I am always getting a partial message. And if the response is short, like 'OK' etc., I get no response at all.There is about 30 ft between the 2 intercoms. 1 in the office and 1 in the basement. Signal is very strong and the transmission is clear, easily understood with good voice quality. Volume can be adjusted to as loud or quiet as you like.The previous intercom I had did not have this problem. It used the house wiring as the transmission medium. Overall, I liked that unit better. But it had other issues from the beginning stemming from the use of internal house wiring for transmission. Plugging that unit into some circuits would not work at all. Plugging some appliances into the circuits being used would compromise the signal.While I am reasonably satisfied with this system. I am still looking for the perfect intercom system.

This intercom is a step saver! I am no longer running stairs relaying messages. The range and clarity of this device is excellent! From 1st pic to 2nd pic below! Vast improvement!

I purchased 5 of these intercoms for my home. From time to time, I would hear loud interference noises and someone talking through the device. I had no idea if someone can listen in to my conversations or eavesdrop into my home, regardless whether or not I was pressing the talk button. I ended up disposing them out of concern for my family's privacy and security concerns. I guess you get what you pay for. Its shameful that with today's technology, this off shore company can't build a home intercom system that doesn't pick up other frequencies, conversations and interference. Also, I should add, that the speaker quality is very subpar. Listening to someone speak over it, is like listening to a drive-in Jack-In-The-Box speaker. The sound quality is very cheap and toy like. The bottom line is that if you have concern that others may be eavesdropping and invading your privacy, or listening to your conversations, stay far away from this product.

love the product ... works well
