    Functional Bubble Counter
  

*by B***N on Reviewed in Canada 🇨🇦 on February 19, 2019*

I was looking for a very cheap bubble counter that could be delivered next day through prime and this was it.  So far it seems to be working fine.  I don't know if this is a long term solution but I am happy with it so far.

    Save your money
  

*by E***C on Reviewed in Canada 🇨🇦 on April 27, 2019*

It is almost impossible to fill with water unless you use a syringe.  I would save your money and buy one that has a screw off top.

### ⭐⭐⭐⭐⭐
