HF is usually pretty good. However, there are only two things I buy from HF: non-electrical hand tools, and things I know I am only ever going to use once. The first because they carry lifetime warranty and are very unlikely to break, and the second because if it was important enough to need more than once, I'll make sure I get something that will last. I got a 10 amp Pro-Logix (only about 2 years ago, and it was almost 60% cheaper than now!
) and it's sturdy, charges great, will work as a tender or a 12V supply for the electronics if the battery is out of the vehicle. I've had a couple batteries that I was sure were ready to scrap, and I ran a couple charge cycles on it and they're still working today.
Remember that HF sells to meet a price point, not to match quality with big brands. Some things may be able to still be made well at the cheap price, but not everything can. It's not HF's fault people think they can squeeze blood from a turnip.Pro-Logix Maintainer
