CR-T7 3.5 inch Colorful Display Multi-functional TFT Backlight Transistor Tester for Diode Triode Capacitor Resistor, LCR-T7Features: 1. It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N channel and P channel MOSFET, IGBT, JFET, triac and battery etc. 2. It can also be used to detect infrared wave forms. 3. It also can detect zener diode and has the function of self calibration. 4. After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully
Features:
1. It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc.
2. It can also be used to detect infrared wave forms.
3. It also can detect zener diode and has the function of self-calibration.
4. After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.
5. One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too.
6. Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.
7. Not like the usual black and white display, this detector will show results in color.

Great Idea but they will let you down eventually
I have used these for years during the winter. The price has nearly tripled but the longevity is the same. I normally purchase three with one being a spare. Within a few weeks they start going. I switch batteries etc but normally that does not help. Its a great idea and my dogs love them but they dont hold up to 10 minutes of play each nite. We do not throw them either, I roll them or kick them as my dogs are older

Great fun for our dogs!
Style: Original
My dogs can’t get enough of this very noisy ball. We have one outside and one in their playroom. It is very noisy. It is very hard. So, I’d say a room with fine furniture is not the place for it. Ours bang it around pretty good.
Our boxer did split one, biting it. But, she’s a serious chewer! Our other dog carries it around sometimes but hasn’t been able to damage it yet. So, I’d say for most chewers it’s going to last a long time.
It’s a great toy but in most households I’d say basement or outside. Again, it’s hard and did ding a few baseboards.
