Rated 4.0 out of 5.0 by Good News; Bad News GOOD NEWS: Three great attributes I’ve discovered are; (1) The spikes are extremely inconspicuous; (2) they seem to give good water flow to the pots without “swamping them” the way my previous drip system did (I can see the damp ground spreading out from one of them; all the plants in 3 pots have been happy for a week now without my watering them, so it apparently works); (3) I’m not paying for so much wasted water (it’s expensive in my area) … I now use 4 drip-line drippers in four water reservoirs where I previously used 12, and have a LOT less overflow of unused water, and (4) with spigots from my drip line watering system (the 3 that used to be in only 3 of my 12 pots on the porch) taped to the top rims of my 3 water reservoirs, and each spike’s water line sitting at the bottom of the 1 gallon reservoirs, this combination keeps my patio pots watered infinitely (like all summer) without my even being home. BAD NEWS: Though the spikes are great, the water delivery line for them could use some improvement; (1) distributor could add an extra 2 feet to the line so water reservoirs for really high patio pots don’t have to be placed behind them on TOP of other upturned pots for the line to reach the bottom of water reservoir. This is a very “messy” look and, though I’ll put up with it for the other benefits, it could definitely be improved on with a longer distribution line. (2) distributor could add a small weight to the reservoir end of the water line; this would keep the wind from blowing it out of the water reservoir in very windy areas (like the one I live in). I’m presently winding the end of the line around extra metal garden attachments I have left over from previous projects and dropping it all into the reservoir….but a simple weight on the end of the line would be much nicer. Again, definitely not a deal breaker (I can work around it) but it would be a nice improvement. April 30, 2013
Rated 5.0 out of 5.0 by Really like Glad to see Home Depot carrying these! Works for vacation plant watering. I have more than one pack. March 29, 2012
Rated 5.0 out of 5.0 by Great Product My plants look excellent after our vacations. I definitively recommend this product. April 14, 2014
Rated 3.0 out of 5.0 by Product was helpful but could be improved. I used this product while on vacation for a week. It ended up keeping my plants alive while I was gone, so I guess it did its job, but I still think improvements could be made. A few useful changes include: more detailed instructions and information about to product and setup, tubing that stays straight (rather than always twisting up), a heavier tip on the tubing or weight to help it stay at the bottom of the water container.

Rated 5.0 out of 5.0 by Good deal These spikes work, and they are a pretty good deal when going on vacation, since I can come back to living plants. I would try them out for a week or so before leaving for vacation, I had to make sure they were actually watering. I followed the instructions. May 23, 2012
Rated 4.0 out of 5.0 by What a handy product Purchased 12 (4 packages) of the automatic waterers and installed each. All are working well and now I'm ready to leave for vacation. Have larger reservoirs for the water needy plants and smaller ones for the dryer ones. Made sure that all plants are above the water source. Installed per instructions and all have worked on first attempt. I am so impressed and my plants are all very happy. Once vacation is over, each will go back to the package waiting for my next trip.

Rated 5.0 out of 5.0 by Best kit Got these because a kit I got by a competitor didn't seem to be able to handle the long planter I was using- got these to place one at each end, and the other company's companion kits accessory was on back order. Have to say that these are the best and it is obvious using these that the other company's kit wasn't doing the job completely. Bought two sets and just replaced the other with this. worth the money! Only wish they came with a resivoir that can hang off the back of the planter (the only reason I bought the other company's kit first). July 22, 2014
Rated 1.0 out of 5.0 by Not worth it Well, it kept my plants watered for about 2 days and then dried up. The water absolutely does not come through the hose into the watering vessel and nearly killed my plant. Not a fan! August 26, 2014
