Dogtra Titanium Enhanced Winged Contact Points Large – Female – E-Collar for Dogs Training – Flexi Fin Design for Sensitive Skin & Contact – Fits Most (Not X Series, 200iQ, NoBark, PATHFINDER2)

We had the original piece that comes with the dogtra. Our goofy boy had no care about it. When training, he didnt seem to even know wed vibrate him. He also would get bare spots where the "prongs" sat. we looked into solutions, and this is a life changer! Seriously. We went from a dog who had no response at all and getting bare spots , to a new response and no more spots!Get it if you have any of these issues.

My dog has a stainless steel allergy so this has worked out well. And he seems far more comfortable in this than the long prongs, but they’ve broken twice. Dogtra has a solid warranty and quickly sent a replacement after a phone call and an email, but I’m not sure they’ll last.

Bought this for my dogs 280C because the original prongs don't touch his skin through his thick husky like hair and this works perfect. It also makes me feel better that it isn't digging into his skin as much. Just make sure to test the effectiveness on your own skin in case the stim is too high or too low.

Comfortable and effective.

I'm a police K-9 handler, I work a young, outrageously high drive Malinois in patrol and narcotics detection. This dog is so driven I have gone so far as to make a Dogtra collar with two 1900s receivers on it. It works well, but it is very bulky. I have a second 1900s system with just the original single collar. I bought three of these thinking they just might spread the stimulation out a bit where the collars wouldn't have to be as tight and I'd get a wider contact area. The contacts are easy to install, my worries about not getting a good contact on his neck were not an issue, and this worked as well as I'd hoped. At least Until they started to break. First the contacts start bending, then the wire breaks right where it goes around the post on the collar. The first one I thought was a fluke, so I replaced it. Then they all started breaking the exact same way. Now I have four of them that are all broken, that's a lot of money to throw in the trash.

My dog seems to be just as responsive, but jolts less at the same shock strength as before. I don't know why collars come factory without this on.

Posting this since a previous review could also mislead others to wrongly believe this is a good purchase for their circumstance. This product worked on my educator e collar BUT when it came time for charging it was not a good fit as the charger plug could not fit with the comfort pad on the receiver. I got a size regular for the right fit, but I do not recommend purchasing this for you educator (e collar technologies) if you do not want to have to remove the comfort pad every time it is time to charge your receiver.

These are an absolute necessity for my very thick coated German Shepherd Dog! Without them, it is very difficult to get a good/consistent connection, They've held up well and are easy to install.
