Agreed. Cordless is OK for the occasional mechanic, but won't likely stand up to regular or prolonged use. The smallish batteries that come with most Ryobis can't run the 1/2" driver for long. I've had a couple older batteries straight up fail on me from overheating or overdrawing them, or something. The 1/2" impact driver came with a large-capacity battery, which gets a tire rotation or brake job done fine.I'm slowly replacing my cordless tools to team blue (Makita).
Have a lot of Ryobi and Horrible Freight stuff, and they're definitely a step below on quality and power. The HF corded impact is gigantic and cheap, but never fails to remove lugnuts, and rusty U-bolt nuts on my Jeep.
Most brands will be fine for the home gamer, but if you use it a lot, you'll be happier with one of the "prosumer" brands (buy once cry once).
