I actually use mine for work, but I’m not using most of them daily. For me I needed variety (the right tool for the job) and them all to be on the same battery ecosystem. They’ve also got some great “widgets”, the 1-gal battery shop vac is around $60-70 IIRC and is an amazing little bit of kit. It’s like a suitcase of clean. The power caulker isn’t a technical marvel but has absolutely saved my wrist on a few jobs. I was on the fence about the power brush but use it a TON around the house. The battery hot glue gun is also more useful than I thought it would be.
I made a 10 amp 18v corded adapter I can use with all the tools when power is available and I don’t want to fry the battery. I also made an adapter so I can USB charge off my batteries if the power goes out or something (they make those but I had the parts).
But I’ve never had issues. It is worth researching each tool though. They tend to have tiers even within the brand (18v vs the HP+ line). The sawzall in that starter kit is… cute. It “works” in the strictest sense of the word. The little circular saw is similar, but there’s a lot more use cases for a lightweight, low-profile circ saw; I love mine. The impact drivers/drills always did right by me. The battery powered chop saw is pretty great (I love that I can just slap a battery on it for a few cuts or use my adapter).
All in all, from what I’ve heard the issue isn’t usually performance it’s durability. That being said, it’s not like I baby my tools, I just don’t use the same tool everyday like a contractor might. IMO it’s a great brand for a ton of people. I think they’re fine for home improvement, just maybe not building a house.
