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.

Perfect for our living room, would buy again!
Color: Rustic Brown and Black, Color: Rustic Brown and Black
We couldn’t add built ins because of our vents so went with theses instead and they were exactly what we needed! Very durable, sturdy, and a great height! Bought one first then decided we wanted another! They look great for decorations plus for our babies toys! Comes with everything you need, drywall screws and all. Would buy another if I need it in the future!

Looks Fantastic, but you HAVE to follow the setup directions!
Color: Rustic Brown and Black
BLUF: I bought this for my office to display photos, awards, and such and I am very happy with the purchase.
Background: I moved into a new house and needed to organize my office. Like most people, I have a bunch of nicknacks, paperweights, and small gifts given over time. And like most people, I had no efficient nor aesthetically pleasing way to display all of the items. I didn't want a big solid bookcase, but more of a display case to show them all off. I bought this and am very happy with the results. I would suggest it to anyone, however it is not perfect.
PROS: Enough shelves with enough space to hold all of the small items that I had. It is solid if installed correctly. Additionally, it is smaller and fits flush against the wall, giving the room organization and improving it, while not overburdening it and making the room feel crowded.
CONS: The main issue is that the single bar going up through all of the shelves makes it very flimsy if you don't secure it to the wall. YOU MUST SECURE IT TO THE WALL PROPERLY!!! I cannot express that more. Once you do, it becomes a solid piece, but it will not function properly if you do not secure it at all 4 attachment points.
Overall: I would buy this again!

Easy to put together, looks great, IKEA similar quality! Everything was there plus the extras to make it 2 smaller shelves. Seems really stable. Love the green color.
