Just closed a pre-seed and my angels all used the RUV, with one exception.

Overall, would _definitely_ use again as a founder. It's incredibly simple and it costs us ~$8K. To the angels, no cost no carry, so it's v similar to investing directly.

Also _should_ simplify our life with lawyers in a series A.

I've been on the receiving end of one three times now, but have never "hosted" one myself. As an angel, I'd probably always prefer to invest directly, but if my alternative were "RUV or you can't invest," I wouldn't object to the RUV.

The process itself is slightly easier because I don't have to tediously type in wire instructions into my bank's website :)

The creator of the RUV can decide whether the company pays the fees or whether the investors pay the fees. The ones I've done so far have been "company pays the fee," in part I think to help avoid the perception that you're getting a worse deal via the RUV.

As a founder I would be quite weary of an entity such as Angelists running the roll-up vehicle, I'd rather have a small committee of trusted angel investors (usually the larger ones) do this instead of some commercial entity.
