Water quality tester

I bought the Membrane switch from JRPanel for the first time and I really appreciate the quality of the product and the attention of the employees of this company. The team of JRPanel make a review and contact me with EQs, to avoid the production of Membrane switch with improvements. Also they give me a better suggestion, which also be very helpful for my future design. The price of the product is very honest and I have sure that I will buy more Membrane switchs soon. Membrane switchs are extremely well-finished and we save money and time. I am very happy with results.
