Do not buy anything you see advertised on Facebook. They are almost always misleading or out right scams. I think out of several things I purchased only 1 was what it was advertised to be. That was a router bit and I probably could have got it cheaper somewhere else.
A couple examples, a digital watch that showed many watch faces and other features. The watch I got only had 3 or 4 analog type faces and did almost nothing that was shown in the add.
Walabot is advertising heavily right now. It only works on very few phones and the App for it is only available on the German Google play store.. Did not work for me.
This summer I saw an add for a small trailer which was 1/3 the price it sales for online. Too good to be true, I ordered 1 and a week later the website was gone. Unlike many of these they sent an email confirming the order and gave every impression they were filling the order.
Solar adds claiming there are government programs that will pay for your solar system. Pure bull shit. Every solar program I have looked into would cost me more than what my averaged electric bill is.
Sticks and boxes that will give you faster internet or hundreds of TV channels with some wonderful product. One of which was a wifi extension that I had seen on Amazon for 1/3 the price it was advertised by someone else on Facebook. Yes you can get lots of digital channels with a device called an antenna. I got rid of expensive cable and dish years ago. I bought an omnidirectional antenna from Amazon that is amplified and I get over 60 digital channels plus all their sub channels on my TV for free. None of these little sticks that go on your TV will work worth a damn don’t waste your money on them.
Messenger scams, I had someone contact me using the name of my Congress man and say he had a government program to help people struggling with their bills that would pay off my house and credit cards. Three different people claiming to work for the government but would not tell me the program or branch of government, it was secret and I was not to tell anyone. They talked to me about this but then wanted me to send money to a private address for “processing fees”. The more I talked to them the more I was convinced it was a scam. Especially when they tried to tell me the FedEx truck bringing me money was involved in a wreck, even sent me photos of it and my money would be delayed. About then the messenger account started showing it was coming from Nigeria..
So my advice is not to buy Anything though a Facebook ads or messenger. Only buy from reputable companies like Amazon or Walmart.
