I drink tea in my tumbler 24/7 and it gets the tea stain from around the rim

Not sure if this stocking stuffer was worth it in the end. It's fine, but it's very prone to being another "thing" in the kitchen that ends up in the back of a drawer. It was inexpensive, which is great, but its worthiness is dependent on actual use.

Could be a little longer. Not easy to use in some items. Good for gifts.

Works great for thermal cups, and all reusables. One on the sink, and one at work, keeps the coffee cup sparkling and the coffee yummy.

Works great, just what I needed for my water bottles!

This is a solid little device. It has 3 brush heads for cleaning various small crevices. Each of the brush heads are pretty good quality. The plastic bristles are stiff and the silicone ones have lots of knubs. The rotating bristles also only rotate in one direction and kind of lock when in position, so it makes it easier to use the brush that's extended. There is one issue which is cleaning the silicone brush part which is a bit tricky. It has these nubs and grooves, but is pretty densely packed and cannot be removed from the plastic body. The silicone is very securely inserted which is good, but also makes it tricky to keep the silicone clean, although you can just stick it in a dishwasher or just clean it as best as you can and rinse off.Overall, it's pretty good for portability. Mostly the little bristle brush on the back is used as everything else can pretty much be cleaned with a sponge or long brush to get the inside of bottles.

these are not great - they are very cheaply made and the one brush side doesn't have a clicked locking system or anything to hold it in place, so when you attempt to use the brush, it just keeps moving... very frustrating.

These water bottle lid/cap cleaners have 3 different types of brushes attached to clean different parts of your cap. There are 3 cleaners that come in the package. The main brush is a silicone brush with teeth on both sides so you can clean the inside and outside of the cap at the same time. The other side of the tool has 2 brushes that swivel depending on what you need to clean. One of the brushes on the swivel part, popped off, but it can be put back on, although it keeps coming off. The only issue I have with the swivel part of the tool is that it doesn't really lock, so when you are applying pressure to clean, it keeps moving and swiveling. This gets annoying when you are trying to clean something. Overall the tool is a great idea, but it needs some work to make it better. The price is good at $9.00, but I don't think you need 3 of them.
