EXCELLENT Customer Service
I requested a refund on my annual subscription after it had been taken out of my account. I explained that I don't use the software, and did not need to have my subscription renewed. The person who helped me was very kind, and responded promptly. I had a full refund within 48 hours! EXCELLENT customer service!

What do you like best about the product?
It's the best tool for PDF editing I have found so far
What do you dislike about the product?
Too expensive if you're not a business user (the price is too high for myself when I need the tool for a few times during the month, so it doesn't worth the price)
What problems is the product solving and how is that benefiting you?
It works perfectly as an editor, so I can easily change my documents with minimum effort.

I really enjoy using PDF filler. I consider my self to not be computer savy at all. I would really like it if there were a webinar to help people like me understand this app.

Great service
Great service. I was able to put together some T&C'S for my business and personalise them by adding my logo and name where nedded.

How I spent an hour filling out fields, then was forced into a trial through the threat of losing my doc if I did not comply with trial? that? that was messed up. the app is amazing. but that first experience overshadows.

I like the signature feature that gives a lot of options. I wish there was a better way to add information and have it look nice, but it does have the flexibility to add something anywhere, so that is nice.

It's been great so far. I need to learn how to move around the dashboard quicker. Also, I need to learn how to set up individual folders (if applicable)?

Excellent product
Excellent product. Easy to use and much better than the others that I have used. Has been very helpful especially when needing to copy info over and so on.

It's essential for digital nomads
It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe

How does a radio work diagram?
1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
How does a radio receiver work?
A radio receiver is the opposite of a radio transmitter. It uses an antenna to capture radio waves, processes those waves to extract only those waves that are vibrating at the desired frequency, extracts the audio signals that were added to those waves, amplifies the audio signals, and finally plays them on a speaker.
How does an FM radio receiver work?
A radio or FM receiver is an electronic device that receives radio waves and converts the information carried by them to a usable form. An antenna is used to catch the desired frequency waves. Frequency modulation is widely used for FM radio broadcasting.
How does a radio transmitter work?
A radio transmitter is an electronic circuit which transforms electric power from a power source into a radio frequency alternating current to apply to the antenna, and the antenna radiates the energy from this current as radio waves.
How do you make a radio receiver?
Step 1: Wind 26-gauge wire (the green magnet wire) around the glue stick until it covers nearly the entire cylinder. Step 2: Strip the ends of the wire you've left from each end of the coil. Step 3: Attach the wire from the right side of the coil to one end of your diode.
How are radio signals transmitted?
In transmission, a transmitter generates an alternating current of radio frequency which is applied to an antenna. When the waves strike the antenna of a radio receiver, they push the electrons in the metal back and forth, inducing a tiny alternating current.
How are radio waves transmitted?
Transmission Of Radio Waves. The radio wave that leaves a transmitting antenna originates as a sound spoken into a microphone. The current is then transmitted to an antenna, where the varying electrical field associated with the current initiates an electromagnetic wave in the air around the antenna.
How are signals transmitted?
The process of sending and receiving radio signals through wireless networks involves two devices, the transmitter and the receiver. The receiver picks up the waves with its antenna or aerial and turns the electric signal back into sound where it can be heard.
