So how exactly I can not judge because I have no comparison Knife If the measured rainfall.
I can not comment on as I have purchased the product only recently that the plastics used to withstand an extended period of weather so far. But I am confident that I will have for a long time my pleasure. The plastic parts are thick-walled and make a robust impression.
The mentioned in another review problem that the plastic ring can be on top of the container twist (for setting the rainfall over a longer period) easily I can confirm. I have but this helped that I have simply removed the bezel, then some documents have wound transparent adhesive film and have the ring then plugged in again. Works very well and unintentional rotation is now due to the strammeren seat of the rotary ring is no longer possible.
That this rain gauge above has no funnel (prevents evaporation of the sample water) is not relevant for me because I will not perform long-term measurements. I want to know if it has been raining for example during the night, the day or sometimes over the weekend enough that I do not have to water the garden. Since a couple of evaporated droplets do not fall so much weight.
For the price, the product is recommended in any case and it is a good resource when planning the garden irrigation.
*** Supplement for durability ***
The rain gauge since the purchase in the open now hangs in one place, wherever it reaches the weather, the wind and the sun. Also over the winter he stays there. So far, the material shows no signs of fatigue. It is therefore assumed that the plastic used is of high quality.
