Would a great timer if it was waterproof. It would seem like something that is being used outdoors in most cases would be waterproof especially something controlling sprinklers. I had one growing season but failed a few weeks into the following season after the control shorted out after getting wet. It performed so well that I thought I would just try another and cover the control as best I could with a plastic bag. It failed after only a few months and for the same reason even after protection.

Waste of time and money. I bought 2 of these lights and both times it only came working half way. they already send it to you mended and soldered. Save yourself some headache and AVOID at all costs.

The banner is exactly as pictured except for one detail: each letter is sent in a package included with a string and a needle and you have to assemble it yourself. For the price I expected it to be able to just be pulled out of the package and hung up. Luckily I opened the package prior to the party. 3/5 stars because although it accomplishes what I purchased it for, I likely could have made it myself for cheaper, since I'm already playing arts and crafts with this might as well have just made it all.
