How do I use it?

Is it difficult to use?
No, it's very easy. An instruction sheet with demonstration pictures is included with the device.

Is it painful or uncomfortable?
No, not at all. In fact, there will be many occasions when you'll forget that you're wearing it. Be sure to keep tension at a comfortable level as recommended. Since the ProSizer™ device was designed by a medical practitioner, it is anatomically appropriate and correct to function as it should with minimal discomfort even when used for extended periods of time. Initially, you may notice some slight soreness as your body adjusts to the traction, and this normally tapers off quickly. In some cases, men experience some minor skin irritation, and we sell foam cushions to correct this.

Is it safe? Are there any side effects?
Yes, it is safe and there are no side effects. The device has no impact upon erection ability, sexual performance, urination or fertility. Some initial soreness may occur which is normal.

What is the minimum and maximum size that a penis must be to use the device?
The ProSizer™ accomodates any penis ranging from 2.5" - 6.5" in length, and any size in girth. If you require extension beyond 6.5" in length, simply purchase an extra set of extension rods.

Will my girth get bigger too, or just my length?
Both length and girth will increase as a result of the tissue expansion. Average improvements reported over a 5 month time period are 26% increase in length and 21% increase in girth.

How big does my penis have to be to use it?
The device is adjustable so it can be used by virtually any size penis.

How old do I need to be to use it?
The device is intended for mature adults age 18 or older.

Will it work for an uncircumcised/circumcised penis?
Yes, the device works equally well for both.

What if I get an erection while wearing it?
No problem. The pivoting base adjusts to the given erection angle, or you may simply remove the device and re-apply.

Will this help my erections get harder?
Yes, many of our clients have reported much stronger erections. This is due to the increased cell activity and improved blood flow.

Will it help correct curvature?
Yes, the device has proved efficient in curvature correction.

Is there a particular schedule I have to follow?
No. You can wear the device whenever you desire. Results depend only on the total amount of hours worn and the amount of traction applied.

Can I wear it 24 hours a day? Will this give me faster results?
No, you should not wear it for more than the recommended time. Doing so will not provide faster results. Rest is required for the cell tissue to regenerate. For the first 2 weeks, the device should not be worn for more than 4 hours per day, and only mild tension should be applied. Thereafter, the device may be worn up to 12 hours per day, and mild or moderate tension may be applied.

Can I keep using it forever?
Yes. Results should continue through continued use.

Can I wear it while I sleep?
Yes; however, it may prove difficult to keep the device on if you are a restless sleeper. The only way to determine this is by trying.

Can I wear it while I'm at work?
Yes. If you have a job that is not physically demanding, the device can be worn discretely under boxer shorts and loose-fitting trousers.
