Two years ago we bought one of the Snowbear trailers sold at Home Depot. I must say that it's been a rather big disappointment in terms of quality and reliability. On the second or third trip one of the cotter bolts on the weird mounting bar for the rear gate came off and the gate actually popped right off the back.
A few months ago I noticed the lights weren't working properly. Upon opening them up I found that I couldn't even get the bulbs out of the cheap mount. It turns out the contact plate at the back of the bulb is this crappy flexed strip of copper that was no longer holding the bulb contact tight. To top it off the wires connecting to the contact were just fitted in with a pressure contact, no solder, no connecting screw. When the contact plate flexed the wrong way the wires just fall right out. The cheapest most poorly made piece of crap that I've seen in a long time. I've recently replaced both rear lights completely. The existing ones were beyond hope of repair.
Other issues with the trailer: bolts with no lock nuts or washers just falling off, enamel flaking off with rust despite regular spraying with oil for rust proofing. Needless to say, my next trailer will not be a Snowbear.
Oh, did I mention the license plate mount - it didn't last six months.
If you have a Snowbear trailer, check and tighten bolts regularly and check your lights before every trip. Keep some spare bolts with lock nuts around. Put some wire on your license plate so you don't lose it when the plastic mount breaks.
