About the product1. A high-performance portable mini size front-end signal amplifying switcher and sound quality processor,
2. Built-in high-performance power processor and signal amplifier
3. For circuit design, Texas Instruments(TI) NE5532 dual operation amplifying chip in top quality acts as the front-end amplifier.
4. NE5532P is tailored for the high-performance audio system, which features ultralow harmonic distortion, low noise, high gain bandwidth or other.
5. Dual FET input widens the dynamic range for NE5532, and sound signal amplification and bipolar operational amplifier.
6. NE5532 audio enhancement technology can correct and recover any signal loss and phase deviation of audio signal system for any reason, reproducing sound and indulging the audiences in the spot effects of enhanced high-low sound, somewhat ideal positioning, definition and brightness.
7. With the audio enhancement circuit, audio system will brighten sound, bring you closer to depth, slenderness and definition, fine treble, penetrating middle and strong and natural bass, placing the audiences on spot.
8. Sound signal amplifying switcher, mainly used to switch various multi-channel signal inputs, such as computer, cellphone, tablet, game console, TV set, TV box, MP3.
9. Additionally with output equipment of signal source or other signal inputs, used for amplifying switch

Worked Great. Save a Near New Tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I got these because twice this year I picked up a nail in my motorcycle tire. The local shops want to sell tires so they won't patch any tire no matter how new.
I used these on two tires, a steel-belted radial and a bias-ply off-road tire. It worked out great, both have been holding air for months now and by doing it myself I saved hundreds of $$$.
These are the best way to pemanently patch a tire that's gotten a smallish puncture.

Good quality, Best for schools and shops.
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I bought this butyl repair patch and the quality is good. I brought it to the school where I’m learning automotive repair and used it as a teaching consumable. Many students tried it, and everyone thought it worked very well. One thing I would suggest for individual buyers: pay attention to the size combinations in the package. For most car owners, you may end up using only one size more often. Because of that, this mixed-size packaging is probably more suitable for schools, training programs, or auto repair shops where different sizes are needed regularly. Overall, it’s still a good quality product and performs exactly as expected.

Look very useful
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Haven't actually used them yet, but they look like the perfect way to fix a flat. As can be seen they come in various sizes depending on what you will need. All you need to get is some tire patch rubber cement and a good inner tire sealer (I picked up a can of Xtra Seal)

Saved me from buying a tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch, Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Took our ancient van on a trip to Florida (from IL) and wouldn't you know we picked up some debris in construction. I was able to plug it however the next morning it was flat again. This time I used 2 plugs to and we were able to get home on that. Realizing this wasn't what I wanted my wife driving around and I didn't wanna buy tires for a van with 250k on it I set out to find some internal patches. I pulled the tire off using a harbor freight bead breaker and some motion pro spoons, used vulcanizing Compound and a dremel and patched it right up. Once the tire is off its a really easy process and I just marked my tire and rim to keep the balance close when it went back together. All appears to be working perfectly with no leaks over the past few weeks. This cost way less than a new tire and now I have more for other holes in the future
