What to know before buying

Listing details to confirm

The listing is inconsistent about nozzle capacity: the package contents specify two, a feature claim says up to six, and manufacturer text discusses a two-nozzle version and adding nozzles to the RS400. Confirm compatibility and the selected kit's actual nozzle count before buying. The stated 8-litre reservoir is also described as 2 gallons, which are not equivalent quantities.

Customer feedback highlights easy setup and maintenance, but reports on reliability, value, misting performance and durability are mixed. Some describe the pump working well and lasting for years, while others report frequent stoppages or breakage within a week. For buyers relying on scheduled spraying, this variation matters because the system's programmability does not guarantee dependable operation. The overall rating distribution is mostly positive but includes a substantial range of lower ratings, so it should not be read as a consistent reliability verdict.

Positive themes

Customers are described as finding setup and maintenance easy.

Mixed feedback

Feedback on reliability, quality, value, misting performance and durability is mixed. Reports range from long-lasting operation to early failure.

Frequently asked questions

The manufacturer says it can spray several times per 24-hour cycle, with each spray period adjustable from 2 seconds to 2 minutes.

How many nozzles are included or supported?

The explicit contents list specifies two flexible nozzles, but other listing claims mention up to six or expansion. Confirm the selected kit and compatibility before relying on a larger setup.

What is the reservoir capacity?

The contents description calls it 8 litres and also gives 2 gallons. Those quantities conflict, so check the capacity for the exact listing before purchase.
