This review is for the Tenga Flip Zero: Black Edition... which is tighter/snugger than the White Edition. First, this review is NOT paid or sponsored. I bought this thing on a whim after an extremely disappointing first experience with the "Stoya" sold by Fleshlight... and let me just tell you, this thing is AMAZING! I've never felt anything more intense in my life. Now, some very important things to note: I am abnormally desensitized down there... meaning I'm not nearly as sensitive as most guys. Those who are very sensitive might find this overpowering or even a bit painful. The suction power, friction, and design of this thing is unrivaled... easily the most intense adult toy I've ever owned in my life. While the "sleeve" is not nearly as soft as the Fleshlight, this is a good thing for me... as the Fleshlight was way too soft, which provided no friction/felt like a loose silk. When you first get the product, don't be alarmed that it comes inside a black plastic/ziplock bag... as the toy itself will be vacuum-wrapped in plastic, which is peelable/comes off. The design is intentionally compact, so it doesn't need a flashy box or case. The toy itself IS a case! It has a MAGNETIC STAND for your stroker, which easily keeps it standing upright even on a shaky desk! The "arms" slide off the stroker, which allows you to open it completely (it collapses outwards). Do this to either apply lube evenly throughout, or simply for cleaning. Those same arms also serve as a DRYING STAND... simply place the arms inside the magnetic stand (pictured above), and with your toy collapsed open partially, place it over the two ends of the arms where it's slotted. I dried this thing in TEN MINUTES by putting it on the stand, and then setting that on my air vent... a unique feature no other stroker has. If you're on the less sensitive side like I am, and looking for a mind-blowing experience... BUY THIS. I am convinced this is the most intense toy on the market. But before you do, heed the following warnings: Warning #1: If you're 8 inches or longer, it will be a tight fit... you probably will be just shy of fitting it all in. The toy itself is I think 7.5 inches long. I am 6.6 inches however, and this thing fits me well/leaves a little room at the end. Warning #2: If you're extremely thick (I'm above average, pretty thick tbh) the BLACK EDITION of the Tenga Zero might be too snug. Go for the WHITE EDITION instead, as the black one is designed to be tighter. Warning #3: You will need a LOT of lube for this toy: that's because the grooves, ribs and spines inside of it are very deep, and the flesh material isn't that absorbent, so you'll want a good 1.5oz of lube per session. Order a big bottle. Warning #4: You HAVE TO ease into this. In other words, don't slam yourself in there and start doing full strokes. You need to give the lube time to spread evenly around or you'll give yourself some "rug burn." Lube the inside of the toy AND yourself generously. Insert yourself all the way in, slowly, then slowly work yourself in and out, while applying more lube to yourself as needed. Warning #5: This toy isn't the best for full strokes (but trust me, the suction is so intense that you won't need them). It's best for quarter/half-strokes with no air inside the toy. This will provide intense suction, similar to a certain extreme form of oral, and will provide a sensation like nothing you've ever felt before. If you read this review to the end, I hope I've helped you in some way. This toy is amazing, but again, make sure you use lots of lube and ease into it, otherwise you may not get the same experience I did. This is my #1 favorite toy after trying 2 from Paloqueth, and 1 from Fleshlight. Don't listen to the bad reviews: decide for yourself. For the price, you'll be getting something awesome if you like it.
