Summary: Good features for the money, not sure about quality control
Comment: I bought six of these. These are the least expensive surge protectors I could find that have significant protection against surges. Why do I say this? Two reasons:
1) Most inexpensive surge protectors only protect for surges between the hot and neutral power lines. Better ones (like this) are called "3 line" surge protectors, with protection from hot to neutral, hot to ground, and neutral to ground.
2) Surge protectors are also rated by the amount of energy they can absorb. You can find very cheap ones as low as 70 joules. These are specified as absorbing up to 885 joules.
These units also have an LED which tells you if your outlet is grounded, which is useful information.
However, on one of the six units I bought, the ground LED does not illuminate. It's not worth the shipping to send it back, so I took it apart to see if I could spot the problem. I couldn't, but the construction is solid and I can verify that there are, in fact, three MOVs (metal oxide varistors - the surge absorbing component of most surge protectors).
I'm sure there are better surge protectors out there, but at this price point, these are hard to beat.
