Hi Hok,
I am sorry to hear you are not happy with your CoopWorx feeders.
First, I wanted to let you know that if you would like to send them back I will be glad to offer you a full refund. We have shipped several thousand feeders and we always try to keep our customers happy.
I will be glad to send you a set of telescoping legs if you would like to try that instead of the stake mount. This would be very stable and you can adjust the height so the feed ports are 18” off the ground.
If you prefer, I could send a longer stake mount post to you if you can tell me the length you would like it to be. I can also make the sleeve longer that slides over the post which should make it more stable. We use a sleeve over the post so when the pipe gets deformed driving it in the ground.
Regarding the water feeder, if the unit is not tilting the cups under the water ports could catch the drips. We designed them small so they wouldn’t collect a lot of debris or break off like the large cups you see on some nipple systems. We switched to a slightly stiffer spring for the water ports a couple of months ago, so if any of your ports have a slow drip that should fix the problem. I can send some replacement springs to you if you would lie to try the,
Feel free to give me a call on my cell at 910-233-0502 to discuss.
All the best,
Tom Carter
