The thing with extenders is, the longer you can wear/use them the better. Unfortunately, that’s not always practical for everybody and even at low traction some devices can be uncomfortable. IMHO, the vac type is possibly better, they stretches the entire length of your dick and don’t restrict anything. Also you have choices. One, you can use the standard rig type of gismo where the base, a ring shape, sits snug around the base of your dick and adjustable arms provide the traction. Or two, some form of anchor below the knee can be used for traction, as in an ADS. Of these, I prefer the elasticised type to the static as they maintain a base tension that fluctuates when walking or exercising that gives the whole process a different dimension. The only problem with the vac type is that if too much tension is used you can develop water blisters, which, although not dangerous, will stop you using the device for a while. Having said that, low tension over a prolonged period is the key element to all these devices, as comfort alone dictates. As I’ve said before, the term ‘stretch,’ is misleading. Unlike manual stretching and jelqing, where a higher degree of force is required, bear in mind that they are only short programs. When using a traction device, long term, your dick only needs to be held at or just beyond erection length. There’s that expression, ‘Don’t let it turtle,’ which in effect is what extenders prevent. How you go about it at night though is a different story…
