🌱 OZMI Plant Self Watering Insert Spikes: 6 PCS Automatic Drip Irrigation Control System for Home and Vacation Plant Watering Review

It's ok. While it is easy to assemble and put out for use, the water flow mechanism only work half the time.Also there is no way to screen on the water bottle so it flops around. If your stake isn't in the ground even or if you have a slope to your ground it's going to tip over.I have to refill the bottles quite often since it doesn't really "regular" the water flow. I think it's a good temporary solution, but for long term it isn't quite what I was looking for.

Left for vacation, everything’s dead. Well at least I tried. Probably good for a weekend. But no time after that We couldn''t get ours to work. Unable to balance the bottles.!

If you push to hard to attach the valve, it renders it useless! and even for the half that I got to work, didn't work very well. I tried to adjust to a really slow leak but it all emptied out after 24 hours with a 2-liter bottle.

I'm not sold on this product. I only haven't returned it because it shows I 'try' to keep my plants alive. May not work well with plants that require dry soil.

I tried assembling it and when I tried to put a bottle of water in it, the water bottle just fell over. They DO NOT hold 16 ounce water bottles. Waste of money!

These items didn't include required tubing and no reference material for set up and use.I can't use them because I have no data to set system up

I like that they are colorful and easy to install. Winding to the right lessens the drips and to the left increases the drips. The heavier the bottle the more it sinks into the soil and this blocks and clogs the spicket!

Only the spike and the drip regulator in this drip system works. I’ve tried 5 various sizes of bottles and non fit. If you use a wine bottle as was suggested in the add, it does not fit the system’s spike and as a result, becomes a breaking hazard. I won’t by these again! In my opinion, they are junk!

Not every purchase is a winner but this one classified as pure plastic crap. The idea is the bottle sits on top of the spike and a small spigot regulates the drip. First design flaw—the bottle has to balance on a perfectly straight spike. There is nothing that holds the bottle in place so it generally falls over. Second flaw—the spigots are really cheap plastic and broke almost instantly. My recommendation is do not waste your money. I’m sorry I did. If I’d seen this in a real store I could…

Interesting design that needs some work. Some of the valves didn't flow at all until I cleared them out with a drill bit. They are very hard to set a consistent flow rate. I would never trust them for set and forget. It would be better if the bottle holder was more secure. Plastic drink bottles flop around a lot. Anything heavy like a glass wine bottle would be questionable at best.

I was hoping to use these on my indoor plants when I’m traveling, but because the adjustable drip is either off or too much, they’re not going to help. I attached a 17 oz water bottle on the lowest drip, it was emptied within 24 hours. And to get the water bottle to stand up straight you need to lean it against parts of the plant, which works on some plants and not others. Gonna still need neighbors to come in and water my plants, these are useless.

The design of this product is on the right track but it needs some changes to be really useful. It is very unstable if any bottle larger than 1 liter is used. If the stack were twice as long and provision made to screw the bottle on to the device, it would be quite useful. As it is I would not recommend it.

While these are a good idea in theory, they are actually completely useless. These are marketed as a watering solution for up to 5 or 6 days, I believe. However, the most that it can be used for is a 2 liter bottle. Two liters will not sufficiently water any plant for under a week. It might be good for two days, but especially during the summer her in SoCal. Just last week, it got up to 115° F. These plants will need much more water to be able to survive.

This works but you can spend almost hours trying to get your desired timing between drops and then, the next day could’ve stopped.

I went on vacation for 3 weeks. Some worked. I noticed that the ones that worked best were wine bottles. They have to be standing straight up. It was a challenge to get them set up. I am still not sure how far to push the spike down in the soil. Should the regulator be below or above so you can see the drops?

Well, I thought these would be really great for easy plant watering but, I’m second guessing it now. These do fit into a water bottle cap well but, it’s not easy to turn the bottle upside down in the dispenser and not have water go all over the place. I have had mixed results - the nozzle doesn’t seem to work consistently. I tested it and a small water bottle and it lasted about 3 days which was great! Then when I replaced the bottle and didn’t adjust the nozzle speed, the next morning water…

Tried it for my outside flower pots.Does not attach to the bottle like it looks. Water can just drain out and the flow control valve is not placed in an easy position to adjust.

From the description and online photos I expected the soda bottle to screw onto the unit. Instead, it just sort of "balances” on it. It’s still too early for outside gardening in my zone so only time will tell if these are worth the money/effort.UPDATE:Just as I thought, getting the bottle to balance perfectly straight up and down if you have good, loose soil is impossible. The spike tips over, the bottle tips over, the water pours out. So I tried propping the bottle. The piece that fits inside

These seem to be hit or miss with them. I used 9 of the 10 during my last 3 day trip. Of the 9, 2 stopped dripping shortly after I started them. They were dripping when I set them up. 1 made it thru half a 20 oz bottle and then stopped. The other six worked fine. Very finicky when getting the drips right. Overall I am happy with the 6 that worked, wish they all would have worked.

I’m hoping to use these when I go away. Trying them in the meantime. I recommend you experiment beforehand, different ones drip faster or slower. So far, they’re mostly doing alright.
