I have one and I actually really like mine! I've used it a ton already and find it very convenient. I looked at the Hotsling first at Target and then ordered the Ruby Toots. Aspen seems to really like it as well. It covers her all the way too. It's not a sling I plan on using for more than a few months though because I have another sling for once she gets bigger. So I don't know about recommending it for bigger babies or toddlers. I just got it for the itty bitty infant stage. And it's doing great so far for me! Sorry you didn't like yours Janice! That stinks!
If you are looking at different type of carrier, I just ordered this one and it has lots of great reviews. It's called the Beco Butterfly Carrier. It's a bit pricey, but I can start using it now and it goes to like 35 lbs. So should last a while.
