Sounds similar to my experience, except back before they were bought out. I got a Morpheus II, and whoever shipped it shipped it pre-filled, and it basically became a disposable lighter. Every single fill after that first use it would just blast out so much butane it couldn't light, didn't matter what flame size you set it to. The only way to light it was a separate source, and the soft flame would be ridiculous, the torch would spit and sputter.
Honestly if I ever get another refillable lighter it will probably be one of those utility torches that has a soft flame option. Just about every lighter company I've been interested in and read about that isn't too ridiculous in price has many horror stories about terrible quality.
