Question: Never used a device like this.  How does it work?
Document: Great idea but so far they haven't lived up to the claims. I purchased 4 units. Out of the box three worked one didn't. Of the three that worked, only two work from any distance further than five feet, until they were turned off and on a few times. If you change out the batteries with the supplied extras there is no difference. The problem seems to be in the plug in device. One thing I've noticed though is that they work from a greater distance the more they are used.
I used the "SVAT WRC101 Wireless Outdoor Remote Control Power Outlet" indoor, in my garage, to turn my Rex Plus dog bark alarm on and off. It was, therefore, never exposed to sub-freezing temperature outdoor. I cannot speak to the problem of malfunction of this switch in the cold outdoors. Used as I did, the remote switch functioned perfectly, since I bought it in February 2009. When I first installed it, the battery in the remote control was drained.
Now if only I could get my front door to open with a remote like they used to do on "Silver Spoons"!! !
Plug in your appliance and then plug the device into an outlet. Now push the &#34;On&#34; button to turn it on, and the &#34;Off&#34; button to turn it off. Pretty simple and does exactly what it's designed for. I like a simple device designed to solve a simple problem and do it correctly every time. And the price was right.
Does exactly what it says. Works from a good distance. Great build quality. Seems like it will hold up well over time. I used it with my outdoor Christmas lights. Good housing and insulation for outdoor use. No hesitation to buy another if/when I need it.
The unit works very well. I like it much better than the single button remotes I have used that toggle on and off with only one button.The one change that would be nice is if they made the on and off buttons raised. Right now they are flush with the plastic body of the remote so you have to press somewhat hard to use them.
This is a great device. I have a stationary bike set up in the basement and a floor fan nearby. When I first start exercising I like the fan off. But after about 10 minutes I need the fan on. Enter the WRC101. I hung a string from the ceiling and tied it to the remote control. It's within easy reach of the bike. So there's no longer any need for me to step off of the bike to turn the fan on or off.
I have purchased two of these. The first one stopped working after about a week. I was going to send it back, but doing so through the mail is a hassle. And besides, I thought that I may have damaged it or something. The second one arrived and works but only if you are very close&#8211;like twenty feet. The application for which I need it requires that I be able to activate it from far away (no farther than the stated range of this device).
This unit started out as a great remote. Worked great. Then right after warranty was out it started messing up. Then got where it would not work at all. Was very disappointed & tried to contact customer support but could never get through . So gave up and ordered a new one. Figuring it is only good for a year...
I purchased this for the reason of distance and through walls. The first one I got never worked and was sent another very quickly. This one worked fine for two days from a distance of 40 feet through a glass door and a building wall. Now I have to actually open the Glass door and step out about 3 feet and then it will work. I am still satisfied with the product and would recommend this Item to anyone.
Answer: Plug in your appliance into the unit, plug the unit into the 110v wall outlet, and then use the remote control to start or stop electric from going to the appliance. So far, works very well!
