Not very happy 4

The product is not accompanied by manual, so it is difficult to distinguish which is used for what.
Of view, the products are low quality. The digital thermometer is OK; the other, I do not count ....
The hairbrush and comb are very rigid skin of the baby. The max temperature of the bath sign tester 38, so difficult to test the true temperature, despite ca, it does not work at all.
I'm currently testing other products, but they do not seem qualitative.
In this case, it would be better to spend a little more and buy sth better quality.
