It is convenient to be able to use the holder of Y company as if it is somewhat wrong. It is nice to be able to improve that you can not take out easily with one hand if you keep it in a lying face so that dust does not get inside.
For cost reduction, tried purchasing. As mentioned, holder holder cup on hand can be used as it is, the cup itself is also solid and very satisfied. It is also good to have a spout. I purchased repeat!
