Purchased this through Techno RV and it was delivered very quickly. I even got some good reading material and videos to help me understand the features of this device. We've used it several times and it works as intended. Hope that it will never have to really be used due to an electrical issue, but I've seen others experience damage without one. Good insurance to have for certain.
I was in the market to purchase a surge suppressor for our RV. After reading the Learning Series on TechnoRV's website about surge suppressors I decided to purchase one that they recommended and sell on their website and am so glad that I did. I rec'd tracking notifications from TechnoRV, as well as technical instruction on the operation of the unit leading up to delivery. Upon delivery, I connected the unit to our 30A receptacle that we had put in at our house and found that the unit indicated Reverse Polarity. The wiring at the receptacle has been corrected. I am glad that we went with TechnoRV's recommendation. Their customer service and learning series is great!
This product worked out of the box as expected with the optional blue tooth enabled monitor. I haven't experienced a power failure yet, but the instructions to set this up and connect the wireless monitor were excellent. Experience with Technorv has been great - - price was much better than Amazon, delivery was as expected and the helpful setup video and instructions are excellent. Good vendor, product and communications - - A+.
This was a really great upgrade from my previous surge protector. This thing not only monitors everything going on at your site, but also is checking your RV electrical system at the same time. I have used this new guard on several trips now and believe it is top of the line equipment. I also recently purchased the wireless data receiver and have it inside my TT. With the push of a button I get all the information from the surge guard display. I like that extra feature. Again I am a Techno RV fan. Thanks you guys !!!!!!!
I have only used these two products at two different campgrounds so far on our ~ 6000 mile trip, but I am impressed with Total Protection Surge Guard, as well as the optional Wireless Display. Within 10 seconds the 34931 (30 amp) analyzed the pedestal and provided clean 60 cycle 118 volts to my rig. The 40301 Wireless Display is so convenient to keep a check on the operation of the Surge Guard and my power consumption at the press of a button ... rain, or shine, there is no reason to walk to the pedestal to check the readout for any errors ! Happy that I purchased these units and would recommend them to others !!
