The CareTec IV Electrical Stimulator is a portable electrotherapy device featuring FOUR therapeutic modes: Transcutaneous Electrical Nerve Stimulation (TENS), Electrical Muscle Stimulation (EMS), Interferential (IF), and Russian Stim, which are used for pain relief and muscle stimulation. The stimulator sends a gentle electrical current to underlying nerves or muscles via electrodes applied to the skin. The parameters of the device are controlled by the channel buttons, with the intensity levels easily adjustable according to a user's specific needs.Relieve your pain with TENS.
TENS stands for Transcutaneous Electrical Nerve Stimulation and is a non-invasive, drug-free method of controlling pain through small electrical impulses. These impulses mask the pain in the treated area and help you carry out daily activities pain free.
Therapy stimulation for your muscles in the EMS program.
EMS, or NMES, is Electrical Muscle Stimulation designed to help treat muscle injuries. This program’s function is to cause muscle contractions in efforts of helping rehab the muscle tissues, along with directly working on muscle motor neurons. This therapy is popular for all muscle-related injuries, muscle re-education, and improving blood flow to the muscle groups.
Reduce Chronic Pain & Inflammation with the IF program.
Interferential Stimulation or better known for short as (IF) is a chronic pain therapy & anti-inflammatory-based treatment modality. Interferential stimulation provides powerful and deep stimulation by using two alternating-currents of different frequencies that work together to produce an interferential current. This current has been proven to stimulate sensory, motor, and pain fibers offering chronic pain relief where TENS may not be strong enough.
Strengthen your muscles and alleviate spasms using the Russian Stim program.
Russian stimulation is commonly used to assist a muscle in strengthening more quickly following injury or surgery. It uses medium frequencies to provide electrical stimulation to muscle groups and can also be used to reduce muscle spasms, as well as for muscle strengthening. Russian Stimulation is an integral part of rehabilitation and healing for many patients.

Great way to connect my Ethernet to my MacBook Pro....
Size: USB C to Ethernet Adapter
Needed to direct connect to my Modem / Router, but my MacBook Pro, being more modern, and slimmer, doesn't have an Ethernet port anymore (thank goodness). This worked perfectly; just plugged it in and ripped...definitely Plug-n-Play for my Mac.
Quality is good (what else do you expect from Anker).

Easy to use Plug and Play
Size: USB C to Ethernet Adapter
The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.
Size: USB C to Ethernet Adapter
For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer.
I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.
