Check before you buy

Regulatory status. Prefer FDA-cleared vacuum devices or FDA-authorized OTC products over dietary supplements. ED supplements are not reviewed for efficacy, and the FDA has repeatedly found hidden prescription drugs in 'male enhancement' products.
Vacuum limiter. The pump must have a pressure-limiting valve. Novelty pumps without a limiter can produce excessive vacuum that causes bruising, blisters or tissue injury.
Constriction ring time. Remove the tension ring within 30 minutes. Longer constriction risks tissue damage. Medical kits state this limit and include quick-release rings.
Cylinder and ring sizing. Choose a kit with several ring tensions and a cylinder sized to fit. Ring tension that is too loose fails to maintain the erection, and a ring that is too tight is painful and unsafe.
Underlying cause. See a doctor before self-treating new ED. ED is often an early sign of heart disease or diabetes, and prescription medications are first-line treatment for many men.

What to avoid

'Herbal Viagra' or 'male enhancement' pills, honey packets and capsules, which the FDA has repeatedly found contain undeclared sildenafil or tadalafil.
Novelty or adult-store pumps without a vacuum limiter.
Using hidden-drug supplements while taking nitrates, because the combination can cause a dangerous drop in blood pressure.
Constriction rings without a quick-release design, or wearing any ring for more than 30 minutes.

Questions

Can I buy sildenafil or tadalafil here without a prescription?

No. In the US these are prescription drugs. Products claiming to work like them without a prescription are unregulated and may be adulterated.

Do vacuum devices work if pills don't?

Often yes. They draw blood in mechanically, so they can work when medications fail or cannot be taken, such as with nitrate use or after prostate surgery.
