Marker is too large for a 90 lb Katahdin lamb ram. Will not fit snug around the neck. We purchased the item based on description which indicated the harness fit small lamb rams.

This harness does not fit very snug. I am using it on my Katahdin Ram and the harness is too big. I have to adjust it every day which is a pain since I have to round my flock up everyday to do this. I'm giving it 3 stars because it is marking my ewes as they are getting bred.

Easy on. Fits well. Tuck the ends in and tie. Has worked very well to date on a Blackbelly ram.

I have had 2 of these so far.
The first one had the lower straps rip thru the leather early in the 3rd season. The second unit made it thru one breeding season but the swaged over side rivets let go within the first couple days when used a second time. I did purchase some small solid rivets and stainless washers and got it back together. I did end up with several ewes not marked but I knew they were bred when I changed colors and they remained unmarked. I'd suggest Premier look into stiching in a second layer of leather at the stress points and using solid rivets instead of the hollow cores since .
I have to recommend the use though mine failed eventually, a very useful tool if marking your ewes is important.

I used this on my Boer buck for a 2 month period. He never broke or damaged it and it fit pretty decent. He was around 18 months at time of use and used it on a dry lot as well as pasture during the day. I tucked the ends up and tied them closer to the body to help prevent them getting caught. It does take a minute or two to "visualize" it on the animal to help put it on...but I was able to put it on him and take it off both times unassisted and without him tied up or anything. I had no issues with my crayon except I should have probably changed it out at some point but one crayon lasted during the entire 2 months for 25 does.

The rivets holding the chalk holder broke, only partially securing the chalk, two ewes lost wool down to the skin. This is not a well designed product.

I tried using the harness on a Katahdin ram and am having very little success keeping it on. Not sure if its me or the design.

Bought the harness well in advance of breeding but the buck wasn't happy in it. He had been shut off from those luscious smelling does and then when we let hin at them we put the harness on him. I believe he considered it an insult. Nest year we will put the harness on him before closing him off from the does, and give him better company. In the meantime the junior buck I have for sale is wearing it to get used to having one on. Harness attaches well but needs a way of taking up the excess straps.

The first Cross Your Heart Breeding Harness we bought broke in the first week of having it on our buck. It got wet and the leather strap at the front of the chest ripped. When I informed Premier, it was very quickly replaced and I have had no problems with the replacement harness.

The nylon harnesses loosen and move, requiring us to check and tighten the straps daily - also causing a potentially dangerous situation, especially since our goats have horns. The Cross Your Heart Breeding Harness doesn't have this problem and is quite secure, even on yearling bucks.

The rivets on the harness that we bought broke in the first week and we were no longer able to use it. It seemed to be of very good quality, that is why I always wondered if the ran got it caught on something to cause it to break. I am interested to find out how other buyers have fared with this harness. We have had VERY good luck with the nylon harnesses.
