I find it hard to believe how much stuff I've bought here in the last couple of years. The quality isn't always there (what do you expect for the prices, right?), so I recommend thoroughly testing stuff before you need to use it in the field. I've had to return a water pump (started smoking when plugged in, didn't pump), an auger (leaked oil like a 1973 Vega), and a solar inverter (didn't invert). But it's always an easy and painless process to return stuff, so I really can't complain. The staff always handles returns professionally and quickly.
The other 10,000 items I've bought there have been just fine. I'll keep buying more stuff as fast as I can print out the 20% off coupons! It's cheaper and lower quality stuff than you'll get from Home Depot or Lowe's, but for the price, who the hell cares? I could literally buy 3 of some tools at HF for the price of 1 at HD or Lowe's.
