Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

DEMON POSSESSED

AnniePug 1/28/2021

I got my K40 a year ago as an upgrade from my LG K8+. I always get an LG phone. I have always had very good LG phones but I sure did get a rotten one this time. I didnt have it 2 months and it got very slow and I was getting pop ups that the System wasnt working. I cannot count now how many times I have had it to the store and talked to customer service. About 3 months ago it started making its own phone calls and I wasnt even touching it at the time. Then I would get phone calls and it wouldnt let me answer them. I have always had trouble keeping my 4G on and we have reset the specs probably 7 times in the last year. I have even backed everything up and reset it back to factory 2 times. This phone has been a joke and the worst I have ever had. Thankfully I am almost ready for an upgrade. I will more thank likely go with an LG but be sure I will take it back if it is like this one.

Mirror letdown

Sailtheseaoflife 1/28/2021

With all this phone has to offer if you dont have wifi at home you cant mirror your screen like lesser devises can. I have a UHD Lg Tv and I cant for the life of me mirror to this or other tvs. A friend had a cheaper Acetel phone clicked share like the lg the tv switched over to mirror his phone with a tap. I downloaded may apps and none just took over the TV and mirrored. Direct devise to devise. It boggs when memory is over 90 . also UI constantly cuts out. Keyboard at time just dissapears then pops up. But for the dollar for dollar I am glad the price was lowered. But control other divices connected It was a letdown
