Suggestion for My Next Device

To briefly recap, my first two devices were a CB-6000S and a Holy Trainer v3 (short), both clones from Amazon. The CB needed just a bit of filing out of the box to fit together properly, plus some sandpaper to smooth rough edges. It was comfortable but started falling apart relatively quickly. The HT also required some sanding; once I got past the base ring, things have been pretty good (though not quite as comfy as the CB). My main complaint with the HT is that my testicles get pushed forward and separated between the ring and tube. This isn’t much of an issue with loose sweatpants or shorts but becomes more noticeable in jeans or Dockers. Suffice it to say, I move slowly when getting into a car.

Except for work hours, which involve plenty of bending and stooping, I’ve been wearing a cage continuously, with the longest stretch being about 30 hours. To be clear, this is my own choice for reasons I don’t fully grasp yet; I have no keyholder and am not looking for one. Comfort is primary among my requirements, but so is having a solid tube. For some reason, at this point, I prefer that I cannot see or touch my penis, which the black tube of the HT does well.

My “dream” device would be a Steelworxx Steelheart, though I’m not sure if it’s worth the price tag. I’ve looked at other Chinese “short” devices and they all seem similar. Options include fully open cages, those covering the shaft but leaving the glans exposed, and fully enclosed ones. Unfortunately, most seem to share a length of about 45mm. As much as it hurts to admit using their measurements, I would likely need a tube length closer to 30mm.

Any suggestions?
