I use these for cleaning sinks around faucets where build up collects anything that you need a small brush it works greatPerfect grip for all those hard to reach areas to cleanExcellent brush for cleaning grout in the shower.Perfect for cleaning sink strainers. My old strainer looks like new. So glad I found these brushes!These aren't bad, I wish the bristles were stiffer but I really loved the silicone edge tip for cleaning the grout of the shower! So overall not bad.I use this for cleaning the extrusion gear for my 3d printer. It does exactly what I need it to.Brushes are better than toothbrushes...they donot harm the wood on cabinets but they start wearing out.The bristle material are sturdi but rubbery.I use them for edges.They help.Im pleased with purchase.The bristles are great, and make cleaning grout and hard to reach areas so easily. I have a set in my kitchen, and one for the bathroom! Great for all those books and angled crannies that are hard to get into!! The bristles are stiff, and don’t become splayed as it’s used! Some brushes splay so easy, and I can’t stand that. What’s the point of being a cleaning tool if the tool becomes splayed, or comes apart! These are fantastic! One flat, one angled, and a scraper. I’m more than satisfied! I’ll buy again.This brush was exactly what I needed to get at tough to reach spots on a tricky to clean bathroom sink (and bath!). It arrived swiftly and well packaged and in good condition. The brush itself is sturdy and has stood up to repeated use, in many cases quite tough scrubbing that’s actually broken other similar brushes. So five stars for quality of construction. The bristles are stiff and great for tackling mould and grime and the shape means it can get into tight corners really well.All in all, this brush has served me much better than more expensive counterparts. It’s solidly made from quality material that I expect will last along time and comes at a really great price. If you need a brush to get into tight spots for cleaning that will stand up to repeated use then this is the brush for you. Five starsIf you’ve found this review in any way useful I’d be really grateful if you could hit the helpful button and let me know :)I buy most things made by OXO Good Grips as they are durable, functional and well designed. This has not disappointed. The brushes are great for my bathroom- I use the blue set from the same range for my kitchen cleaning. These ones are fab for scrubbing in the nooks and tiles etc and getting the mouldy bits from in between the shower screen and around the neck of the taps etc.Saves me always having to keep an old manky toothbrush for cleaning!I purchased this product for deep bathroom cleaning around taps and in grout lines. The product arrived today and I tested it to remove filler dust that had fallen between floor tile joins. As the pictures show, it is very effective. The rubber point was expectedly effective for the above task. The bristles are firmer than that of a firm toothbrush which is better for suborn cleaning. Is comfortable to hold and effective to use. I hope it lasts.i saw other people had stated you get the same performance out of a used toothbrush so was reluctant to buy but the difference is greater than that. yes, sometimes an old toothbrush will do but these are better because of the angle and the strength of the bristles. i have a 5 pack of toothbrushes from the pound shop for things like trainer bottoms but these are kept for less filthy, more worthwhile jobsA bit disappointed. I wanted them to scrubb off the burnt bits in the grooves of a Circulon non-stick frying pan. Although they are very well made, comfortable and accurately designed, the bristles are not stiff enough and they just get softer and more useless in warm water.The description suggests they would be good for tough jobs. I am sure for more delicate and precise jobs, they would be fine.Full marks to Amazon though as they have offered to refund with the minimum of fuss.
