Advice Needed for Chinese A086 Device

I just picked up an A086 unit from Ebay for a mere $20, including free shipping. The listing says it’s “stainless steel”, but we’ll have to see how accurate that is. I suppose you get what you pay for.;) I’ve searched around, but I’m hoping to find updated pros and cons from someone who actually uses the thing or a similar model. Currently, I’m wearing a Rikers tube which obviously has to be taken off every 3 or 4 days so it can be cleaned. My girlfriend wants me to locate a chastity solution that lets her keep me locked up for much longer stretches while still allowing removal for cleaning, and she feels a steel cage device is the only real option. However, I’m not in a position right now to spend big money on a superior MM product, so I have to settle for the affordable Chinese options. What do you think?
