This AnyWear clip is great for putting the transmitter where you want it. I find it much more useful than the belt clip when wearing a long shirt or jacket. You have to be careful, however, not to press buttons on the ET-300/400 while removing it from the clip since they're on the side and could be easily pressed. Also, the 3mm screw that came with the clip to attach the magnet to the transmitter was too long and bottomed out and left the magnet rattling on the transmitter. I had to cut the screw to fit but most people don't have a tool to do that and would need to find a shorter screw.

Just got this magnetic holster for my Educator Pro 900.

I love how quickly I can grab my remote now or hang it back on my clothes without fussing with a belt clip.

So far it's stayed on though don't know if it would if I was running. It sticks out a little and might catch things.

A little disappointed I couldn't install the remote magnet without taking off the belt clip. It would be nice to have the choice, so say if I'm doing something that requires more security I have a choice.

I tried to install the magnet on tip of the belt clip but the magnet washers won't sit flush then. Maybe if they redesigned the belt clip a little.

I want to see if the magnet will work with the other holster that they sell.

But otherwise I love it. Will go well with my magnetic balls.

PS: Gotta be careful you don't turn your collar back off if holding it when putting your magnets on your body.

I also have a metal plate on my phone for a magnetic holder in my car. Now I can use this holster for my phone too!
