Nowadays, it is becoming more and more difficult to find really high-quality things on the market. Many manufacturers are constantly looking for where to save even more. And because the quality of products is constantly falling. This is best seen in the instruments. It is even worse because more and more often outright consumer goods and even fakes appear on the market. A simple trick will help in these conditions to distinguish a solid screwdriver from a poor quality one.
It is becoming more and more difficult to visually distinguish a high-quality screwdriver from a low-quality one. Even fakes and clones of products of popular brands made in Asia today can look extremely convincing upon initial inspection. At first glance, in order to distinguish products of different quality, you need to be a highly qualified specialist with a trained eye. However, in reality this is not the case. It is enough to pay attention to one single detail.
Where should you look? In fact, everything is extremely simple - first of all, we are interested in the battery tool. The fact is that in most "mediocre" screwdrivers, not very high-quality batteries are used. You can find out this first of all by the number of contacts. In an expensive battery, there will be at least 4 of them. Even better if there are 5 contacts in the battery. High-quality electronics is many times more expensive for the manufacturer itself, and therefore they will be installed only on a tool of the highest standard, capable of serving faithfully for more than one year and more than one hundred hours.
Of course, anything can happen. Sometimes even such a trick will not allow you to recognize a low-quality screwdriver. Very rarely, the creators of "consumer goods" show unprecedented cunning and use batteries with additional dummy contacts. In this case, only an integrated approach will allow you to distinguish a high-quality screwdriver from a low-quality one. It will not be superfluous to look into the data sheet and turn your attention to the tool gearbox. A good indirect evidence of quality is the manner in which all kinds of inscriptions on the instrument are made.
