We have a Bubba Moe. I am quite petite though and I can't get it to adjst small enough for me, so the buckle digs into my shoulder when it is as small as it goes. I also have a Bubzilla sized sling that fits me perfectly. DH can use the Bubba Moe with no hassles. If it helps the Bubzilla site has videos showing how to put it on and the different carries. I prefer videos to diagrams.
