Hi all!
I hate to chime into this conversation, but I will.
I have a THG E-11. Mine is the uni-body design. I think much like everything else in the Legion, there are pro's and cons to every buy.
I agree that it took longer than I would have liked, but that is VERY common in the field of props. I have had extended wait times from very popular sellers. So to me, I'm not sure if that is a knock on Ron.
As far as the cast, mine was not perfect, but it was VERY good. My counter and scope are very crisp pulls (unlike pictured above). I did have a bubble in the screw on the body, but I just replaced it with an actual screw.
One thing I will say is that I found my version of E-11 VERY VERY VERY VERY hard to paint. I have since found out that using Rub & Buff is better than paint on his older style. I think he addressed it with his new formula, but I wish I would have known. To be fair, I'm not sure if the struggle was due to my inexperience with blaster building, or the product itself. I would just want to note, if you are struggling with the paint, I found that I basically had to let it dry for like 2 months. I'm not a chemist, so I have no idea why. Long story short is that it eventually dried.
As far as customer support... I'm in the middle of the road. I'll say that Ron is a really nice guy, and he DID try to address all the issues/communications that I had with him. An all out ban is probably a little unfair. I will say that the first blaster body he sent me was a bad pull, and when I addressed him about the issue, he sent me a replacement right away (which meant a lot to me).
I think the best part of the THG is the detail. A hyperfirm is lighter and easier to deal with for sure. But the cast I got has so many amazing details that carried over from the original gun. Perfect no, but very nice.
All that being said... if asked by a new trooper about a "low effort" approach to an e-11, unfortunately I probably now recommend a Hyperfirm. THG is suited for a more experienced / seasoned builder.
