Delta Controls Differential Pressure Switch

These were the best things I found to organize my wire from my light to my pressure switch, would highly recommend these.

The remote pressure switch works very well and looks great! B&H is great to work with and delivered promptly.

Easy to use. Dip switch controls explained on chassis makes sense.

Works very well. The variable pressure zoom is perfect, and it has a switch for s - Sony and p - Panasonic, which are the 2 video cameras I have, and the switch works as expected. The record button works fine, but you do need to push it for a millisecond. If you hit it for a short time, it may not start recording. This may be the camera though, just something to be aware of. Overall, really great for simple remote zoom and great cost.

When you switch lenses under pressure, you don't want to waste time trying to also switch the filters from the old lens to the new one. This is even more important if you drop the filter, smudge the filter, sneeze on the filter, etc, etc. You can save a lot of grief by investing in enough of the Tiffen 812 filters to avoid this possible mini-disaster. I bought a couple of these filters when I was choosing the lenses I would use for a wedding shoot. It was wise to choose the industry standard in a warming filter. The Tiffen 812 is amazing in flattering flesh tones.

They are used on Sony DSR PD170 camcorders. The switch is pressure sensitive which allows you to manually control the zoom. I really cant say anything negative. They are exactly what we needed for a reasonable price.

I find the earcups very comfortable with even pressure all the way around -- especially making good contact below the ear. The sound quality is excellent for listening to acoustic and acappella music. There's no audio delay like you get with Bluetooth. The volume roller is so much easier and faster to use than buttons and is located exactly where my hand expects to find it. The on/off switch has just the right amount of delay -- long enough so I don't accidentally switch it, and fast enough so it's not annoying. Works out of the box on Windows 10. They even include instructions for how to remove the battery for recyling (which -- more importantly -- means I can replace the battery!) My only complaint so far is that I can't turn off the LEDs without installing their gHub software. But once they're out of warranty I may just fix that with a soldering iron... I'll be using these for all of my daily on-line meetings, and for listening to music.

I purchased the hub assembly to tie my 2 Delta pros into my manual generator switch box (6 circuits) back up power to my house. The first one was shipped and I tried it out. It immediately tripped and error 553 showed on both Delta Pros. I called the customer support number and the rep helped me troubleshoot over the phone. She then forwarded the case to the engineers and it was determined that the power hub was defective and a new one was shipped immediately. The new unit works well and now my kitchen, living room and master bed room are powered at the flick of switch. No more running extension cords and unplugging appliances when back up power is needed. I tried to balance loads on the circuits, but if you run the microwave for long it pulls down one Delta Pro quicker than the other. As they discharge I may have to switch Delta Pro Hub inputs to help balance the unit loads. I am pleased with the support and service from ECO Flow and this hub also frees up the 120 volt outlets on the front of the Delta Pros. When I tie in the solar panels I will upgrade to the smart panel and extra Delta Pro batteries..

The paper has very good range, minimal bronzing and gloss differential.

Well worth the price differential for added features and ease of use.
