You Need This Gadget

On this page you can find gadgets and interesting products and some comparison that can help when deciding on one product or another, in general a useful website with enough information, the companies that sell the products seem serious and sell worldwide and every week there are new gadgets.

I have come across this portal, and I really have my doubts about the products it reviews. On the one hand, it shows branded products, which look very suspiciously like other high-end products at a very low cost.

One of the products that attracts the most attention, are the copies of the Apple smartwatch, which under the names of eWatch and xWatch, are sold with a difference of just $15.00 and both below $100.00.
Can you see both in the next url:

I finally bought both to compare and see if the service is really good. I have reviewed and they are practically the same. Although apparently they are sold through two different companies.
The same goes for different types of products, such as stop barking, TV signal boosters, heaters and several more. The question I have is whether this use is made lawful of small differences with brands. Is it legal to take advantage of this or are you really selling low quality copies of the original?
Judge the photos yourself.
I made a purchase in each of these to compare the products, and they seemed almost the same, unlike the application they use. They also offered me to pay a one-year warranty, when it is mandatory to give a two-year guarantee throughout the EU.
On the other hand, it seems that they belong to other different companies, and this only makes the reviews. The question is whether they are really accurate. In the case of watches, it seems that they really are.
