This has been the only set of brushes I've found that are actually able to scrub the bottoms of my tall water bottles. So glad I bought these! Great valueThe bristles and shafts on these brushes are definitely designed to last. The handles are suffer than most every other brush we've bought, and the bristles are soft enough to get into hard corners yet stuff enough to remove 3 day old coffee residue.Didn't realize the brush heads were the same size. Still very good, would but again if needed. Like the variety of themI mainly bought this bundle for the longest silicone brush it came with. It seemed to be one of the longest online at the time for a good price and I really needed it to clean off algae that started growing at the bottom of my 5 gallon jug. I needed something that would easily reach the bottom and this worked perfectly!Now, I have to note that my 5 gallon jug has a wide opening so I can still fit my wrist and arm through. If this was the kind of 5 gallon jug with a smaller opening, then it might not reach all the way and needs to get extended, which is still pretty doable. Overall, the quality is there, it's easy to clean, and it cleaned the algae off the bottom of my jug very well.Bottle cleaning brushes are great - I always had the bristle brush which sheds and traps dirt. This silicone brush is great, the lengthy one is great for long bottles and the head is small enough to wash the bottle caps. But the straw cleaner is not long enough if you have lengthy stainless steel straws. that’s the only downside, otherwise great productIt's not full enough to reach the top parts of the bottles. I would return it if possible.These help to be able to clean out tall bottles. Very easy to use and help get in the tight corners.These work great for my steak and kitchen knives. I’ve bought a lot of knives lately and I have had a few issues when I clean them, I get cut because the sponge has my hand so close to the blade.I got these brushes to allow my hand to stay further away from the blade and still clean the brushes. Works great. Very simple and much safer.
