Upon delivery I immediately tested this device. Initially it was 5mm off at a distance of 1m so I calibrated it. Then I tested it at 2m and it was bang on! I can't check it at longer distances because I have no other range finder to compare to. . Angle measurement is accurate within 0.1 degree so it's perfectly OK. I haven't tested Pythagorean and area measurements because if distance measurements are accurate then so are area and Pythagorean measurements. . The display is well illuminated, easily legible in broad daylight, too. The whole device has a professional look and grip with the aluminum case. . Last but not least this was one of the few range finders with free shipping to Hungary. But the ultimate reason for me to buy it were the thousands of satisfied customers and the lack of negative reviews. . Absolutely and highly recommended!

This is a very good product. I primarily bought it for its ability to measure inductors and the ESR of capacitors. Multimeters with these capabilities are rare and not cheap. I have experienced one minor issue with this device but with some attention it doesn't cause problems. It's as follows: The battery voltage measurement is very inaccurate, see the photo below. The device measures 7.3V and says OK whereas the real battery voltage of my almost depleted battery is 6.2V. This is a problem because the dropout voltage of the 7805 linear voltage stabilizer on the PCB is 2V. So while the device "thinks" that its supply from the 7805 is 5V it actually is only 6.2-2=4.2V which leads to some inaccurate measurements. So make sure you use fresh batteries. The 40 seconds auto shutdown helps conserve the battery. Apart from this I'm very satisfied with this product. Highly recommended.

This is a good and versatile charger. Below I'll give some additional info you won't find in the user manual. 1) Short touch any key to turn on the backlight. It will stay on for 30 seconds, then it will automatically turn off. 2) Long touch the Current key until the beep tone stops. This will turn on the backlight permanently. Repeat this two times to turn the backlight off. 3) The charging process of Li-ion batteries will will be terminated at 4.22V but the display shows 4.20V. This is +0.48%, barely within the usual tolerance of +/-0.5% given for other chargers. I wish it were closer to 4.20V. Other pieces of this type may vary. 4) In Discharge and Test modes Li-ion batteries will be discharged to 2.82V. This is no problem with the charger, this is the usual way to test capacity but not so good for the battery. So don't use these features too often! My personal opinion is that the max. discharge current of 500mA is too small, it takes 15+ hours to test a 5000mAh battery. This is way too long, I miss an option for 1000mA discharge current. On the other hand you don't test batteries even on a weekly basis, so you can let the charger take its time. 5) Disconnect the USB input cable to enter USB power bank mode. The device draws 150mA from the battery in standby mode, including the backlight, which is always on in this mode. With a load of ca. 1300mA it draws 2A from a full battery. At first glance it may seem bad efficiency but it is not because the 4V battery drives a boost converter to produce the 1300mA at 5V. This requires ca. 1625mA from the battery, plus the 150mA standby current. So the efficiency of the boost converter is 1625/(2000-150) = 87%. This is very good. All in all, this is an excellent product, very good value for your money. Highly recommended!

This is an excellent product. The contents of the pages are well chosen, page 1 (photo 1) shows basic information, page 2 (photo 2) shows ALL information and page 3 (photo 3) shows the voltage and current curve. With the curve on display you can choose 4 time ranges by pressing the button for about 0.5 seconds: 5 minutes, 15 minutes, 60 minutes and 2 hours. This is a VERY USEFUL function, 2 hours will be sufficient for most loading tasks. Note that changing the time range will clear the graph (but not the cumulated data on page 2). The user manual describes a calibration process but it does not apply to this product. The no-load current is precisely 0.00000A (photo 4). Highly recommended!

JLG Toperform its function it needs to be connected to the power source that you measure, if it is the USB port of the PC, it must be connected to the PC, but if you measure a different source, you can connect the tester via Bluetooth to the PC and follow the readings there.

farkasditke73 It is a rotary encoder rather than a potentiometer so it hopefully won't wear out so fast. However, an optical sensor would be much more durable.

Мышка симпатичная, работает хорошо. Но есть один недостаток: примерно через год ее можно будет выбросить, потому что, как я смог разглядеть, колесо использует не оптопару, а потенциометр, который со временем сотрется. Зарядка через порт USB-C. Датчик видимым светом не светится, полагаю, УФ-лазер. Отличный сувенир. Упакована очень аккуратно - красочная коробочка из тонкого картона вложена в жесткую, чтобы не помялось. Лично мне не хватает боковых кнопок навигации.

farkasditke73 Strictly speaking the emitted light is not laser so there's no need for a laser marking. An internal laser source is used to excite the phosphor: LEP, Laser Excited Phosphor. If it were laser the light wouldn't be white.

I'm not a gamer so I don't need a mouse with many buttons. This basic mouse is exactly what I need: smaller than average in size (my hands are smaller than average, too) and a flat design so it doesn't strain my wrist. My laptop has only two USB-A sockets so the mouse's Bluetooth capability comes in very handy. Additionally I can use it with my tablet and phone, too. A lot of much higher priced mice have no Bluetooth capability. It's a shame that the RGB light can't be turned off. It goes out in about 40 seconds but lights up again whenever you move the mouse. Maybe I'll solder out the RGB LED. The built-in battery is a removable unbranded button-top 14500 with a capacity of 250mAh as measured by my LiitoKala Lii-M4S. It takes less than an hour to fully charge a depleted battery. Unfortunately the mouse doesn't seem to have overdischarge protection, it's still working at 2.8V (my LiitoKala Lii-M4S stops discharging at this voltage), or it kicks in at an even lower voltage, which is not so good for the battery. All in all, this is an excellent mouse for general use, especially for people with smaller hands. Highly recommended.
