    AT34 Multi-function USB3.0 Color Display Tester - BLUE
    მივიღე 18 დღეში, ნიდერლანდების რეგისტრირებული გზავნილით, კარგ მდგომარეობაში, შეფუთვა ნორმალური, ნაკეთობა შეესაბამება საიტზე განთავსებულ ინფომრაციას, ცოტა არ მომეწონა ის, რომ ციფერბლატის, ზოგიერთი რიგი, კერძოდ მე-3 და მე-4 ქვედა მარცხენა რიგში ძალიან პატარა ზომის სიმბოლოებია და ძნელად იკითხება. ჩვენება ზუსტი აქვს პატარა ცდომილებით, მასალა რითიც დამზადებულია ტესტერი საკმაოდ მკვრივი და კარგი ხარისხისაა, ფუნქციონალურად საკმარისია, არა პროფესიონალი მომხმარებლისთვის, კვების წყაროებისა და ნაკეთობების დასატესტად, მოუხერხებელია მხოლოდ ერთი ღილაკით, რომ იმართება. მთლიანობაში მე კმაყოფილი ვარ, მადლობა "GearBest" !

    Tester with excellent manufacturing level
    Tester with excellent manufacturing. Visible on the visible board is clean, neat, without sagging and flux. The screen is good! The text on the screen is clear and readable. To increase the information content of the inscriptions displayed in a smaller, but readable font. The text can be seen at a significant angle of inclination. Functionally, the tester fits the description. The product matches the description. I am pleased with the purchase.
    I recommend to buy.

    Doma mám väčší počet zariadení, ktoré majú USB porty. Keď som objavil tento tester, rád som si ho objednal, pretože ako bývalý technik mám rád kontrolu a samozrejme dostatok informácií o mojich zariadeniach, hlavne "zdraví" dobýjateľných batérií. Prvé skúsenosti s testerom plne zodpovedajú mojím očakávaniam. Ďakujem a odporúčam nákup.
