REVIEWS: Senao 358 user reviews:




I am an owner of a bigger house in Netherlands, and I wasn`t satisfied with the phones that we got from our local phone service provider, because the range is very small and it barely covered the half of our house.

Now we finally have Senao 358 PLUS and I have the range all over the house, backyard and I can even go to the store or a local bank and still have the connection.

I wish to thank the gentleman from R&R electronics for giving me a very good choice.

I am very happy with Senao 358 device, I think is the best cordless phone I ever used. For my job top priority is to be connected everywhere in the seven storied building and outside range of about 700 m. To use Cell phones was is very expensive and not good for my health, since they have high power and high frequency 900 MHz and it was made me have headache every day. Also since on Senao 358 handset power is only 450mW and on low frequency 264/355MHz that is 100 X better to use for my health than Cell phones.
Now I have free intercom connection between base and tree handsets, everything work in prefect way. I have better solution for my job, health and business is more profitable.

All best recommendation for SENAO 358 and R&R Group

I am a receptionist that works in a huge warehouse that holds a lot of building materials for distribution. Since I have to be all over the warehouse I had to find a solution for not being able to answer the telephone at the front desk. My boss bought me a Senao 358 plus. This phone is the perfect solution because it is direct line to only me, which I can be reached at during the whole day no matter where I might be in the warehouse. So when the phone rings at the front desk and I am not there. The call is automatically transferred to my Senao 358 telephone which I answer right away and it is a great advantage for our company.

I am very satisfied with Senao 358plus model. My business mainly depends on telephone calls I receive. For long time on my work place I had only cell phone, my customers called me on my cell phone and because cell conversation cost a lot I start to lose costumers. Now I can freely say that after I bought Senao Long range phone my business improved and I gained new costumers.

I am used cars salesman and I work in a large yard in Johnstown, Pennsylvania. Because I have two dogs, Labrador Retriever, Alex and German Sheppard, Rex, I have big problem when I have to take them for a walk, because I need to be near the phone all the time. Before I used to walk my dogs in a backyard, but since I have Senao 358 plus phone, I can go to park as well and still be available for my employees as well as customers. This means a lot to me.

Cuando abri un negocio hice tarjetas de presentacion con el numero telefonico de mi casa, tiempo despues rente unas oficinas cerca (3 kms) y compre el equipo SN 358 + con antena exterior; ahora puedo contestar las llamadas de negocio usando la linea de mi casa. Tambien compre una extension adicional para mi esposa, asi ella puede tomar llamadas de sus amistades y familia y transferirme las llamadas de negocios, otra ventaja es poder salir a atender algunos clientes alrededor de 15 kms y poder contestar cualquier llamada.
Comprar este equipo fue la mejor inversion para hacer rendir mi negocio.

En Guadalajara tengo varias bodegas producen ropa de moda por toda la cuidad. Como no puedo estar en mas de una bodega a la ves compre 4 teléfonos 358+ Senvo. Estos teléfonos me permiten estar siempre en contacto con todos los encargados de las bodegas. Como es teléfono Mobile es muy caro y con menos estabilidad que el Senvo. Era mucho mejor usar el senvo, me permite ser mas eficiente y estar mejor comunicado. Es el mejor teléfono que e comprado en todo mi vida.
