Senao 258+new1 user reviews:

My job is to be the head of a construction site for a company from Turkey which builds residential districts. It has always been a problem for me to be in contact with my workers and other employees at the same time. After I bought Sn 258+newl, I am very satisfied. We use it at the construction site in combination with 10 headsets, we are always in contact, which makes us more productive and faster at our work.

I think that this is a much better solution and at least ten times faster than before with toki walkies. This way we have a base at my office, I call them over the intercom, or more than one person at the same time and we have a phone line and a toki walkie.

You can say that we are finaly connected.

I am a retired woman in the age of 65 and I spend most of my time cooking talking over the phone and drinking coffee with my neighbors. Of all those things my favorite one is to talk over the phone with my friends for hours.

After I saw my friend bringing her phone at my place I decided to buy the SENAO 258+new1. I simply wasn't aware the freedom that the phone would give me. Now I can bring my home phone line to my friends or when I go to the store. I can talk as much as I want for the price of regular phone impulses and always be available for the phone calls I get.

I am a farmer from Texas. In our place mobile phones don`t have any range, so our only connection with the world is the regular phone. Also whenever I worked on the farm noone could reach me. Thanks to my smart friend I found out about the phones that R&R electronics sell. After viewing their web page I concluded that the model Senao 258+new1 suits me best with it`s performances and it`s price because I don`t get along with phones that have a menu and a display.Senao 258+new1 is and ideal phone for me. I finally have a connection all over my property and neighborhood, and I can easily say that

I wouldn`t trade it for any cellular phone.

My father is very old and he lives next to a Volcano named Paricutin in Michoacan Mexico he has cattle and a small farm. He does not wish to use mobile phone because it is complicated for him since he is so old. I bought him a Senao 258 and only showed him which is the call and end key because this telephone is so easy to use and he loves it now. Now I can get a hold of him all the time when he is out with the cattle or a home. It is the perfect solution to our communication problems. Since my father has owed this device all of his neighbors have asked where he got it and I have installed four more telephones since, it is the perfect telephone for there everyday job for all those who live in this small town.
