Interesting Dremel Accessories - Proxxon Brand

Just one quick question, with the proxxon chuck can you use any dremel type and size accessory or are there any limitations because of having to leave the collat in order to use the chuck? I have a rotary tool with a flex shaft and really need a quick chuck because it's annoying having to chance bits. But where I live the proxxon chuck is 7 euros and the dremel is almost 19 euros, hope the proxxon one works because these prices are ridiculous.
