I tried using a normal bike pump to fill up my inner tube and it was taking forever so we ended up borrowing an electric pump from a relative which did the job but still took a long time. Fast forward a couple months and I was with another relative who had the High Output Air Pump Double Quick II and was impressed with the performance and it was made by Intex. So I went on Amazon and checked out the reviews and they weren't as good as I was hoping, then I saw the Double Quick III which had much better reviews so I took the plunge and I bought it. Now I just had it arrive today and tried it out on my inner tube and I am extremely pleased with the results its just what I was looking for it pumps up my inner tube way faster than my bike pump and the electric pump I used. I would definitely recommend this product.
