I have over 100 palm trees planted on a couple rai of land. I purchased a considerable amount of "Super products" from the above mentioned shop. The Rainbird stuff is excellent but expensive. The so called Super Products are junk. It is all made of cheap plastic that quickly gets brittle in the sun. The hose, mainly the small 1/4" drip line, more or less useless. Within a few months it was and is cracking/splitting/leaking at the push on water feed connections. Unfortunately, I have yet to find a quality/uv resistant replacement in Thailand.
