Recently, friends have been asking me in the backend whether those promotional products marketed as "long-lasting condoms, delay type, buy one get one free" are worth buying. To be honest, the waters in this industry run deep. The most common mistake beginners make is being tempted by bargains—seeing "buy one get one free" and thinking they've scored a deal, only to end up with a product that not only feels terrible but can also cause skin allergies or even more serious health issues.

Let me start with the conclusion: these promotional products aren't necessarily off-limits, but the prerequisite is that you know how to pick the right ones. Many low-priced items marketed under the "gift series" banner are often overstocked inventory or defective products of unknown origin. Even for legitimate branded products, even with discounts, the per-unit price typically falls in the 3-8 RMB range. If the price is significantly lower than that, you need to be wary of whether the materials and lubricant ingredients are up to standard.

How to identify a reliable delay condom?
The first trick is to look at patented technology. Brands I usually follow, for example, typically label their packaging with ultra-smooth silicone lubrication technology or layered composite lubrication technology. These technology patents can be verified on relevant national websites—they're not something you can fake with just a random sticker. You can check out market-tested brands like Mingliu Condoms to see whether they have a comprehensive anti-counterfeiting system.

The second trick is to examine the ingredients. The so-called "delay type" essentially involves adding local anesthetics like benzocaine. The biggest pitfall for beginners is excessive dosage. Many inferior products add excessive chemical ingredients to chase the so-called "quick effect," which not only numbs you completely but can also cause discomfort for your partner. A proper delay condom should have a mild sensation, with the delay effect typically lasting around 10-20 minutes, rather than that intense numbness that leaves you feeling "nothing at all."

Regarding usage methods, many people buy condoms but overlook complementary products. In reality, relying solely on the condom's lubrication is often insufficient, especially when pursuing endurance, as friction increases. At that point, pairing it with some lubricants is what seasoned users would do. However, be very careful not to use oil-based lubricants randomly—they can corrode latex. For specific pairing advice, you can check out this article on safe combinations, which covers the details thoroughly.

Additionally, if you feel that relying solely on condom delay isn't enough, there are also products like delay wipes on the market. But these fall under the category of external-use medical devices, so you must check the approval number carefully when purchasing—never use unbranded, unlicensed products. If you're still unclear about lubricant materials, I recommend referring to the lubricant review to understand the differences between water-based, silicone-based, and oil-based options. Don't treat your private parts as a testing ground.

Three pieces of advice for beginners:
1. Tiered budgeting: For entry-level, choose basic models from major brands; for advanced level, consider patented models with delay ingredients. Don't try to buy dozens of boxes for just a few dozen RMB—that's definitely a tax on your intelligence.
2. Safety first: If any redness, swelling, or itching occurs, stop using immediately. Even with well-known brands, everyone's body has different tolerance levels to ingredients.
3. Channel matters: Always purchase from official brand websites or legitimate flagship stores. Those gift series of unknown origin, no matter how many freebies they throw in, should never be used on your body.

One final reminder: endurance isn't achieved through "cheating." Condoms and auxiliary products are meant to make the experience more comfortable and give you more time, not to let you overextend indefinitely. Maintaining good lifestyle habits is far more effective than buying any amount of high-end gear.
