Overview
The Metrel Installation Tester is designed for compliance testing to the AS/NZ3000 standard. This multifunctional device is suitable for testing appliances and installations, combining the capabilities of 12 instruments into one highly specified tester. Specifically built to meet Australian standards, it provides the ultimate all-in-one testing solution.
Clever accessories, such as the optional 3-phase adaptor kit, allow for easy deployment of the tester in various environments. An optional resistor box (not included) can be connected to the switchboard during installation testing, eliminating the need for lengthy trailing earth leads during outlet socket testing. Built-in thresholds deliver clear results with PASS/FAIL indications in accordance with AS3000 specifications, similar to an appliance tester.

No assembly required
Color: Light Beige, Size: 6-Panel
Absolutely love this! Arrived in a timely manner and it’s very versatile. Blocks the light on our porch on a hot day. Very durable and stable product. The color was as expected and there is no assembly required.

Looks ok if you don't look too close. Not likely to last long.
Color: Light Beige, Size: 6-Panel, Color: Light Beige, Size: 6-Panel
Got here fast, which was great since our company "upgraded" its video conferencing software and virtual backgrounds no longer work. But I can only describe the item as rickety and sloppily built. See photos: visible gaps in the weave that show the frame through. Chewed up screws in the hinges look like someone took them out and put them back in several times... or salvaged them from another unit.
On the whole, it doesn't seem sturdy. I'll be folding it up and re-deploying it several times a week, so I'll be surprised if it will still stand up in a year. Not a good value for the price, really, except that demand on these right now has prices pushed upward. I'd be happy enough if I'd spent $39.99 rather than over a hundred.

Excellent Customer Service
Color: 3 Panels Natural, Size: 3 Panels
It is a nice looking screen but when I opened the box, it had been damaged in shipping. I am giving a 5 star review because of the customer service I received. They were more than accommodating (so important when dealing with a large item such as this).
