I got the City Commander and Protector kits, then had to put them and other stuff in storage, then they REALLY got kept in storage when we moved, and by the time I got back to them they had been passed by and outclassed. I remember being impressed just by the facility of creating something so involved from scratch, even if the designs were a bit... Lacking (Protector did work out a bit better). I did jump at the chance to get their Bruticus add-ons, as high on the Unicron Trilogy as I was.
Warbot Defender was what made me tune RIGHT out, because even at the time that was... woof. An interesting learning experiment for the designer, but not something I'd ever buy. Assaulter looked better, but also one I never seriously considered -- due to the other thing that was keeping me well away: the steep pricing. Then, as now, 3P stuff is just prohibitively priced due to various factors, which is just as well.
I did backtrack and get a surprising good deal on their Quickswitch, which at Voyagerish height and as a unique mold is preferable to the TR Velocitron set light retool of the character.
3P stuff has come a really long way in the... Near 20 years since then, yikes.
I've picked up a couple of their things on deep clearance, Quickswitch and Glacialord. Both are well done and a lot of fun for the price I paid. Glacialord especially is fun as the whole idea of "Late G1 toy from an alternate dimension" style toy is something that you just don't really see people doing. Not sure it worked out for them financially, as it seems you can still find unsold stock of those at several retailers all these years later, but I think they're great.
