I definitely think it's worth it as it was a good fit for my buying criteria;
- compact, discrete, self-contained and locking. I've got two small kids in the house so this was a must.
-turn key. I've got very little free time so I didn't want to invest the time (and endless trips to Home Depot) to do it myself.
-fire safety. It's professionally wired. If I did it, it definitely wouldn't be professional.
Is it worth it from a financial standpoint? Sure. You can build it yourself cheaper if you have an aptitude for that. I spent $5,000 on it and harvested 525 grams first crop (before I lost 100 grams to rot while drying in mason jars, not the fault of the machine). Before I had this box I was paying $10-$12 per gram at my dispensary. By that metric it paid for itself with the first crop.
