Anyone ever use an M-Wave trailer? What's your experience with it? I can get one for under $170.

I have no experience with any of them, but it looks like there are a lot of m-wave models. It might help if you narrow your question a bit by model.

Never seen any.. what did you want the trailer to do..?

I just googled it and seems as though everybody and their brother sells them. I couldn't find a mfg site so that concerned me a bit. I also read that it connects via the chain stay. I would take a closer look at that piece of it. Nice looking trailer otherwise.

Shipping weight=33 lbs, so the trailer itself weighs ~30 lbs.

A BOB Yak weighs 18 with the Yak Sak; a Burley Nomad weighs 14.5. The BOB Yak trailer without sack weighs 14.5 lbs.

I don't know how Mwave managed to make their trailer twice as heavy. Dimensions and pictures indicate it's about the same size as a Nomad. I wouldn't want to tow something weighing more than a Yak and Nomad combined, day after day. Also it has knobby tires, so you'd want to swap those for slicks eventually.

It would be fine as a grocery hauler. Since it's $198 shipped from Amazon, I'd be inclined to wait (if I could) for a good deal on a used Nomad, which would cost the same or less.

Last December Burley had Nomads marked down to $186 shipped on Amazon; Flatbeds were $140.

Looks like a pick-up. No reason it shouldn't be sturdy, but a base weight that would allow you to fully equip 5 people ultralite style, does seem a little heavy. What is your intended use?
