This shipping was fast. The install and setup were very easy. The only disappointing thing is we have to pick them up and talk into them to understand each other. We have tried everything from low to high volume and different distances but still we must pick up and talk into which is very inconvenient especially for the price. Otherwise I love everything about them.

I purchased the set of 2 intercoms for our home in December. I live with a senior family member, and there's 3 floors in the house. Yelling doesn't really work, going up and down flights of stairs to check in or ask a quick question isnt practical, and while we can text, they don't always have their phone with them. I thought this would be a good way to check in with each other, and generally communicate when needed. It works great for our purposes. I have purchased a third intercom so we now have one on each floor. The sound quality is fine, think of what a decent walkie talkie sounds like, that's basically what this intercom is.

Considering we are using these intercoms through three floors, on opposite sides of the house, I'm quite satisfied. When you speak through one, it can be heard through both other units. We have yet to experience any interference or other ppls conversations through our units, and our home is directly adjacent to others, in a busy area of a city. Whether or not our conversations have been heard by others, I wouldn't know, but I kinda doubt it, most ppl don't use these sort of electronics in their homes anymore. We don't really have conversations or discuss anything personal or sensitive; just use it to check in with each other, ask a quick question, etc. The opposite end of the power cord is a USB A connector, that can plug into the included ac plugs, which is great. I have two units running through the USB connection, and the third through the ac plug. We just use the " talk " button to communicate, there are other functions, but tbh, I didn't read the included instruction manual to figure them out. Just being able to talk briefly between diff floors pressing the talk button is really all we need these for. Also, they have been knocked over onto the floor multiple times, and once got some water on one, and they still work fine, so I'd say they're durable and built well. The packaging it comes in is quality also.

I'm sure there are more high end models with crystal clear sound and that work across longer distances - even other models by this same manufacturer- and different ways to communicate through your home, but for us, this works great. The value is great for this two pack, it's currently on sale for less then I purchased them for, but I'm satisfied with its quality at the price I paid, it's just right for what you're getting.

I'm giving these intercoms 5 stars because it's just what I expected, and pretty awesome for our family.

It's as easy as plugging it up but the volume could be a lot louder. It's all right I guess. Meh.

these are nice, the sound glitched a bit but this seller really stands behind their product and made this right

I originally bought the WL666 model, however, I was not happy with it since it made static noise. The quality was not good. So I returned it for a refund. The seller then contacted me and offered to send me a newer model: S600, free of charge. I accepted his generous offer, received the unit. The new unit, model # S600 is excellent. If I had known it previously, I would have bought it. Now I have a free unit and I am very happy with it. I highly recommend S600 to everyone looking for a high quality intercom.
