I use a product called The Mexicans quite regularly. This product, The Mexicans, has a lot of good features. It works reliably, is quite cheap, and has very little upkeep costs (a case of Corona every now and then). The Mexicans is heat tolerant, does exactly as I want it to, and can easily be replaced. While there is no warranty, replacements are very affordable making this a non-issue.
The Mexicans is a product that is readily available. One can find The Mexicans at most Home Depots (parking lots), and other fine establishments where similar lawn and garden tools may be found.
I have tried similar products and found them to be much more expensive, not work as well, and can give me significant problems (especially if I abuse them as I'm apt to).
My only problem with this product, The Mexicans, is that my government is passing unreasonable restrictions on it. Recently the product has become much more difficult to find, and there is talk about my government making my favorite product completely illegal and entirely unavailable. The Mexicans has very real value to me, and I would hate to see my government change the product (like when Yoplait changed their recipe and made their yogurt disgusting). If you can figure out a way to protect The Mexicans product the way it is, I would very much appreciate it.
