Let me preface this review by saying I’m a mom of 3 boys so cleaning toilets is a full time job! After using this toilet brush for the past two weeks, here are the pros and cons. 
Pros: The brush easily cleans the hard to reach areas, such as under the rim and inside the hole. My last toilet brush didn’t reach those areas well; so when I used this one for the first time, it removed a ton of grime. The brush is lightweight and the bristles are spaced in such a way that it drains well. Also, the storage case makes it so easy to remove and store the brush. The entire set is small in size and nests well behind the toilet. 
Cons: The handle can be a bit slick when you are wearing gloves to clean. The brush could be improved by adding a rubber grip to the handle. 
Overall, this is a great set to add to your cleaning routine and I highly recommend it.
