Has had this system since November 2017 and initially it felt half-finished but a number of "obvious" functions that were missing. Since then it has matured and I have been very pleased with it since it gave me good coverage throughout the house (wooden house, about 150 sqm) and also on the plot. Had I written this review a month ago, it would undoubtedly have been a full pot, but unfortunately TP Link released an update about three weeks ago which was then withdrawn quickly. The update has more or less rendered the system unusable. Instead of sending out a new update that solves the problems, one has not done anything at all. This has nothing to do with Deco as a product, but I would imagine before I buy anything at all from TP Link in the future.
It should be added that those who buy the system today are releasing the wrong software, but one should keep in mind that they (TP-Link) will probably react as slowly next time somewhat stray.
