Received this product eight weeks after ordering it. The packaging was damaged and the box crushed. However, the two principal components appear to be undamaged. Both the transmitter and the receiver switches were in the "ON" position draining their built-in lithium batteries. I am charging the units now and hope that everything will work as promised. After recharging the batteries, my first test was successful and it was clear that you have to elevate the volume of the receiver to pick up the probe's signal from 25cm distance with no earth or concrete obstruction between the transmitter and the receiver. I will test an empty conduit in the wall with 3cm of concrete between them and give feedback on this later. So far, I am happy with the product. The long delivery time was not the fault of Banggood, it was the fault of their shipping partner, "SFC", who did not provide accurate "Tracking Info" as to where the item was being held for over a month. Thanks, Banggood, for your excellent customer service that finally located the product and alerting me where it actually was on hold.

Looks well-built. Tested these RJ45 Couplers and can certify that all pin-outs work perfectly. Arrived very quickly. I am also pleased.

Both UV-9R Plus HT's arrived in good condition. After charging and programming with a Baofeng cable, I tested the VHF and UHF frequencies over a distance of about a kilometer, in some cases with two or three story buildings blocking the line-of-sight. The signals were received loud and clear, with very little static. I tested TSQL and DTCS tones and codes to open receivers. They worked perfectly. Overall, I am very happy and will buy more units for my neighborhood watch teams. The units look rugged, not cheaply built. They appear to be "splash proof", not "water proof". How long they will last is not known, but if they perform for a year or more, I will be very satisfied.

I received the UM4 Intelligent USB 4-slot charger. Disappointed that it doesn't come with any 18650 26650 21700 batteries displayed in the advertisements. Full testing of IMR, Li-ion, and LiFePO4 testing will have to wait. I am testing with some old NiCad and NiMH batteries. So far, I am impressed with its ability for each slot to separately test battery health and charge appropriately.

The NITECORE E4K compact EDC flashlight definitely appears to be a very high quality light. Came with a 5000 mAh battery that with the V6 LEDs is blindingly bright even in daylight. Also has a CR-123 battery sleeve, a pocket clip and a sturdy belt holster. Can't figure out how to install the wrist strap, but probably won't use it. If E4K holds up over time, it will be well worth the premium price.

I have not used these RJ45 plugs yet, but they appear equivalent in build to more expensive name-brand Ethernet plugs.

This 5V 5-port network switch has a much smaller footprint than my Ubiquiti, NetGear, and LinkSys switches. Preliminary testing was good for two of the four pairs. I will make further tests to verify full Ethernet network functionality. Its small size is a plus for many installations. Overall, I am pleased with this switch.

"5 Stars" for quality of material, design, and build. Received the DANIU 433mhz electronic key today and was impressed with the outward quality compared to the OEM original 433mhz devices. However, I deducted "2 Stars" because, after carefully following the instructions in the box on cloning the DANIU product from an original key fob, I was not able to connect to my system. The blue led flashes on the DANIU, so its battery must have power. I will report back when I resolve the cloning issue. Here is a limited user manual in English from DANIU: http://img.banggood.com/file/products/20161027204431NEW English User Manual.doc

Received the two UV-9R radios remarkably quickly, less than 11 days. Both appear to be in good shape, EXCEPT one radio is missing the belt clip "button", a plastic piece that the belt clip slides on to. See attached photo of empty box and all content to verify missing item. Also note that the screws for the belt clip "buttons" are almost 3mm too long and have to be filed down. None of this takes away from the surprisingly high quality overall of the product. I will buy again and suggest others buy also.

Tested the UV-9R Plus using other HT's, including a UV 5x3 with excellent results over varying terrain, with walls and buildings blocking line-of-sight, up to about a kilometer. Strong signals and clear reception, no static at any point. Used the included programming cable with CHIRP to program several UV-9R radios with no problems. Did not use the microphone, headset, nor cigarette lighter charger yet - will report on them later. UV-9R Plus appears to be solidly built, more likely "splash proof" rather than "water proof", so I do not recommend that you drop it into a fountain or swimming pool. I do miss the VFO/MR button on other Baofeng or BTECH products to quickly change from frequency mode to memory channel mode. This model requires turning off the radio and back on while pressing the menu key to do this feature. Overall, I am very happy with the looks and performance. I will buy more of these radios shortly.

YF-4 0.1S-999H Adjustable Cycle Delay Timer Relay Module with Digital Display Timing Delay Board 12V DC
US$8.93 US$13.99

Q: How do you get 5 Amps OUT? 12VDC power goes IN to program P1-6: "After T1 delay time, the relay releases. After T2 delay time, the relay pulls in and repeat the cycle." The program runs the timer, but NO power cycles out at any time, even though the OUT light is on. Please help or find a better product that works as described.

Delayed by COVID-19 lock-down of mail service. Thank you Banggood for forwarding by Red Pack courier delivery service. Appears high quality and the packaging was excellent. I bought a second unit from Amazon because of the mail delay and will give a detailed performance review and comparison later. Very impressed with Banggood.

Appears good, but lacks user guide and mounting screws or snap in base. Will hook up to a 12 volt, 5 Amp circuit and test it for review later.

Q: Is there a base to mount this timer. It looks like it is designed to snap into a base unit, there are no holes for screws or bolts.
