Cloner Plugins

So I've been using React 2 for a couple of months — 2026 update when???? — and it does the job just fine, but sometimes I find it a bit slow, especially when working with cloned images. I know there are similar plugins out there. I already tried Cloners + Effectors, but I had to get a refund because it was pretty much not working.

I was wondering if anyone has experience with xCloner. The developers claim that the plugin is super fast, etc. The promo videos look nice and promising, but before I buy it I wanted to know how it performs in practice. Is it really that fast and reliable? Maybe someone has other recommendations for this type of plugin?
