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.

Still 4 stars
Format: Kindle
A little to much before and to much dive into the days, months before, but I still kept reading. Maybe because of that you could read about them all. I just couldn't put this book in my to read another day list. I just wanted to know what happens to them.

Promising but not without issues
Format: Kindle
First off, the FMC and the pack don't meet until about 60% of the way through.
That's just way too late honestly. I can appreciate the backstory of the band and the FMC, but I skimmed at times wondering when they'd meet.
I did like the writing and premise but I thought the execution needed a lot of work.
The characters were pretty well developed, but they didn't spend that much time on the page together, so I thought that led to the story suffering.
I will give her another shot, as I think the writing has promise... It just didn't come all together in a way that I could wholeheartedly recommend.

DNF
Format: Kindle
I really tried to finish this book. There was too much detail in more than half the book. They do not even meet for. Ore than half the book. If you are looking for spice, this is not the book for you. This is more a late teen if that. I stopped reading when she made her choice of men for her first time. There isn’t any urge to read the next chapter. Easy to put down.

All The Things!!
Format: Kindle
This is definitely worth reading! The spice is nice, but the story itself is truly an epic literary treat! Tessa and her Alphas are a powerhouse force of nature who will capture your heart. This story is also a great reminder of how fickle life can be and how quickly everything can change for anyone. Every single person, billionaire to janitor, is nothing but one tragic event away from being in the same situation as Tessa was in. ❤️

Kind of difficult to get through for the first half but worth the read!
Format: Kindle
3.75/5 ⭐️
What this book lacked in being fully polished, it made up for in world and character building for sure!
While the first half was hard to get through, as this is a book that starts you in the present and then goes back and forth between different times in the past to get you up to speed with what’s happening in the future (and it’s not all chronological in the past which made it even harder), once all of the book is set in the present, Tessa and her pack, Ryder, Dixon, Mac, and Tray, (and of course Josie the cat,) all begin their journeys of finding themselves both individually and within their pack which is so rewarding to see after all of the tragedy and sadness detailed in their last few years leading up to meeting. I think this book could’ve done with another beta reader or two to polish up grammatical errors as well, some of those took me out of the story for a minute to try to figure out what was trying to be communicated.
Overall, this story filled with so many dichotomies of love and loss, grief and happiness, hurt and comfort, all culminating in a lovely story of a pack that strengthens each other after many tribulations, and it warms your heart so so much to see them go through every version of themselves, landing on secure and happy individuals who make a wonderful pack together.
Would absolutely recommend if you like slow burn, rockstar, big city, and initially heavy and a bit dark but fades into comfort and fluffy omegaverse stories!
