I will try to list each product and a review. I hope this helps.
All products have been tested to the same standard and have been approved by the FAA for use on airplanes. Most of the time these products are available on Amazon. Some are not, I will discuss that in the next section. There are some products that are very low cost and have very good results, but the main reason is their low price. These products are usually labeled "affordable" because the product cost is less than $10. These products have some other things going for them, too, like that they have a lifetime warranty and you don't need to go back to your first purchase. There are other products that are more expensive, but that do a better job, but not quite as good. They may have a longer lifespan and a lot more features. This will be the second article on the list. So, for me, the only time a low cost product is good is when the product doesn't cost a lot of money. It's a great place to start. In this first article I'm going to take you through the best low cost agility products.
