Correct. The vacuum type gives you more comfort over the noose and
strap type. But when your glans is irritated, the noose/
strap type helps for a period of time over the vacuum. I believe the
Stealth Stretcher has both noose and vacuum for usage. Always have a system that can support multiple kind. I think
PhalloSan Forte and the Plus series also have that as well.
Correct. The cost is due to the design features. The
SizeDoctor shapes the vacuum cup to be similar to the your glans. I can't say the vacuum cares about that. What's the most important is the glans enters the vacuum cup correctly, and the seal around the base of the glans works without any issues. This is the most fundamental function of the vacuum system, which is the sealing function at the base of the glans.
The
Stealth has a leg
strap, or waist
strap, along with extender base system, while the
Size Doctor uses extender base with spring loaded system. The
Size Doctor can be strapped like the
Stealth Stretcher by purchasing your own leg or waist straps, based on your own comforts. Look at the
SiliStretcher2 for more ideas. Most
strap kits don't cost more than a fast meal in town. I purchase my own materials from the local craft stores and made my own revisions for additional comforts.
Like most ADS and extenders, they are interchangable in
strap system. If you type "penis stretcher
strap" to the Google search, and switch over to the Images, you'll find at least two dozens
strap ideas. They range from a simple and cheap straps to comfort and extravagant deigner straps. Look carefully to what you like, since your tastes are different than mine.
