This teleprompter does the job but the build quality is okay, feels really expensive for the price you pay. There are cheaper analogues with a similar design. It's lightweight and portable. 50mm thread missing. So far I'm fine, but if I buy a lens with a 50mm thread, then this teleprompter is useless for me. The remote control is hit or miss. You may have to press the keys multiple times to get the action you want. In summary, this is a good teleprompter that gets the job done. It would be very nice if the retail price was around 50.
