Customer photo review of CA - K1 Kenwood (2-Pin)

This thing is built like a brick shithouse. No doubt it’ll withstand whatever you want to throw at it. Very happy and confident that it’s the last PTT for this rig that I’ll have to buy.

Customer video review of CA - Hytera - HYT4

The constant able is far superior to any of the PTTs I've used in the past. Works very well with the Hytera HP782. My only complaint is that they don't have more options for other radios, because I will be buying them for my other radios when they come out.

CA - Hytera - HYT4

Store owner replied: That's a valid complaint - all we can say in defense is that we're working as quickly as possible to fix it, and we appreciate your patience. Thanks for taking the time to review, and enjoy the new gear

Customer photo review of CA - Motorola - GCAI (APX/XPR)

I was having difficulty finding a PTT that was compatible with the TEA SAR-M low noise headset. And this cleaned up all my complications. Can’t recommend this PTT enough. For reference I used the APX/XPR plug on an XPR model radio.

CA - Motorola - GCAI (APX/XPR)

Store owner replied: Mackenzie, thank you for the review, and that's great that you're so stoked. We're glad we could help you out. 🫡

Customer photo review of CA - Motorola - GCAI (APX/XPR)

I’ve now had a few weeks to test and use this ptt. I must say it has quickly become one of my go to push to talks the ergonomics has become my new standard for push to talks and have had zero issues with switching between headsets no matter the wiring type or mic impedance. Disco32 has really raised the bar with this compared to the u94 style that I shied away from. The only thing I’m waiting for that could make it better is for a hi rose version to come out.

CA - Motorola - GCAI (APX/XPR)

I T&E'd this unit for a couple months and ran it through every environment I could think of and had ZERO issues! It's small and compact, out of the way but the button is very tactile so you can't mistake pressing it. It holds to my vest extremely well and never fell off during any activities or operations I was on. I would 1000% recommend this unit!

CA - M9 Motorola GCAI (APX/XPR)

This is the best unit when using Beofeng Dm32/um32 and Comtac 5. Works better than the peltor unit.

CA - K1 Kenwood (2-Pin)

Works perfectly, shipped promptly, and arrived sooner than promised. Excellent quality sound and transmission.

CA - K1 Kenwood (2-Pin)

The folks at Disco 32 were very responsive and knowledgeable! I will be purchasing from them in the future for sure!

CA - M16 Motorola Mini GCAI (N30/R7)

Great product. Only downside was the cord was somewhat short. Shipping was fast as well! Thanks!

CA - K1 Kenwood (2-Pin)

Store owner replied: Samuel, the Constant Able downlead is a standard 20." Let us know if this wasn't the case but great to hear you're happy otherwise

Build quality is absurdly good. Lives up to the hype.

CA - K1 Kenwood (2-Pin)

The online tool to identify the correct PTT for my set up was easy to use and why I followed up with an email to Customer Service, they were prompt and provided great advice. The PTT I purchased works flawlessly and I am very happy with the product, and with the Service from Disco 32!

CA - K1 Kenwood (2-Pin)

Had an issue with the PTT. Customer service was great, and had me send back the PTT to see if they could recreate the issue. Replaced unit with no questions asked.

CA - M9 Motorola GCAI (APX/XPR)

Works as expected. Had a small issue getting it setup. Sent and email to customer service and they got it resolved right away.

CA - K1 Kenwood (2-Pin)

It works great and the ergonomics are nice having the ptt shield and having it at an angle really makes it nice👌

CA - K1 Kenwood (2-Pin)

Store owner replied: That was the idea! Thanks for letting us know how it's doing

Perfect comms. On time delivering and shipping. I have spent quite a bit of time communicating with the company. Again prompt and expedient comms. 10/10 woukd recommend.

Store owner replied: Monty, thank you! V glad you're happy and come back if you need anything else

I really appreciate the customer service from this company. The employee I was connected with to help me was at the Shot Show in Las Vegas. He took time to speak with me and told me the product that I needed to fix my problem. Then switched me back to a young lady at the company who already had been informed of what I needed!! My PTT arrived quickly as well and it is a top quality product!! Wow, that’s just an awesome way to conduct business!!! Disco32 you are the best!!

Store owner replied: Hi Ralph, so glad you're happy, and thank you for taking the time to give us feedback. Much appreciated - reviews like yours are why we're in business

Great product amazing customer service!

CA - K1 Kenwood (2-Pin)

Store owner replied: Thank you for letting us know! Why we do what we do

The Disco 32 Constant Able PTT is a hands down winner. The form, function, and construction are top notch. I love the tactile feel of the transmit button. Plus the shroud around it to prevent an accidental hot mic is simple genius. As with every product I’ve purchased from them, there is no better substitute.

Store owner replied: Troy, this is great to hear. The mantra here is intentionality - we appreciate you taking the time to let us know how it's going.

Just what I have been looking for. Doesn't matter which headset I grab (we have Peltor's and OTTO's), just plug-in an go! This type of cross-platform solution is exactly what is needed for teams where budget limitations are forcing us to do more with less, and to sometimes work with a mix of equipment. Great product!

CA - Motorola - GCAI (APX/XPR)

Store owner replied: Thank you! This is why we do what we do. Very much appreciate the feedback 🫡

Excellent quality PTT, just as advertised! Item shipped out the next morning after purchasing on your website ….. much appreciated! Very user friendly, too.

CA - K1 Kenwood (2-Pin)

Store owner replied: Very glad to hear things went as expected. 🫡

I sent in a question regarding my current set up for PTT and the staff at Disco32 was quick to respond with great information and recommendations. Ended up purchasing their Constant Able PTT with the Kenwood 2 pin connector and the audio quality with both my Howard Leights and my Peltor’s is amazing. Also love the quality of the PTT and the sense of comfort that I get from knowing it’s IP67 waterproof/dust proof rated. Will definitely purchase from again.

CA - K1 Kenwood (2-Pin)

Store owner replied: Thanks for letting us know. So glad you're setup is working so well - come back for more whenever you're ready, and enjoy the gear!

Works great. I ran into an issue (at no fault of the company) and reached out to the support team who quickly resolved it for me. Superior product and customer service.

I ordered the Constant Abel from your website after I watched a video about your product. I received the product very quickly and I hooked it up to the radio and Peltor headset. I turned on the radio and it worked great. Thanks for a great product . Charles Ward

Worked exactly as described, took out the guess work of needing to pick which headset and mic type.

CA - Motorola - GCAI (APX/XPR)

Store owner replied: Awesome. That's all we want. Enjoy the gear

Best PTT you could ever purchase. I had many obstacle with between my headsets, PTT and radio connectivity. Hi impedance, low impedance, was a really difficult issue. The Constant Able PTT fixed all connectivity issues. Highly, highly recommend. Disco 32 knows their stuff.

CA - Motorola - GCAI (APX/XPR)

Store owner replied: Shael, you put us through our paces but we're happy you're happy! Problem solved, problem staying solved ✋

Disco32 has phenomenal products as well as always innovating with regards to the communication space. I have always had a positive interaction with this company, and since they are made here the United States, it adds to the credibility in their ability to provide services to individuals like me in the civilian sector as well as military law-enforcement agencies.

Store owner replied: Thank you Isaac. Civilian, military, LE... we're proud to support all of you.

Ordered the CA PTT. When it showed up I plugged it into the radio and it was so quiet I couldn’t hear so I did everything I could to troubleshoot the radio, PTt, and headset on my own. Reached out to disco 32 and they walked me through so other steps but it didn’t work so they had me send it back with the radio for them to troubleshoot. Had another one back within a week working great. The product is awesome but I’m giving 5 stars mainly for the customer service. They really put me first and helped me out when I had an issue

I had an issue with my original PTTs and DISCO stepped up and made it right. The Constant Able is a great PTT and solves previous connectivity issues I had.
