It took a long time, more than 2 months, already opened a dispute. But the parcel came, so the dispute closed. The package is packed well, the package + puffy. Took for 109r, included 4 pcs. Plastic hard, works. It is necessary for 3 weeks to leave, i hope such watering will help that the plants do not turn into cacti. In fact, it is convenient if plants need regular watering or need to leave for a while. In fact, i already tried. Suitable as large bottles for 2l, 1,5, so smaller volume with a standard neck. Everything works, drips perfectly. Water supply can be adjusted, easy to adjust to your needs. To water dripping without interruptions, you need to make a needle puncture at the bottom of the bottle after installation in the kit there is an instruction with the calculation of water for a time. Thanks to the seller for the quality inexpensive product!
