I've dealt with them for 4 years and never had a problem. Last year Binford drove out from his house in town to the warehouse at 10 pm to package up a dozen queens that his office staff forgot to leave on the warehouse steps for me (I was driving between Houston and San Antonio and made the 50mile detour to ensure the girls were well cared for).
If you ask to talk to Laura she'll call you - she is very nice, but she lives in Austin and is not at the warehouse where the shipping goes on. I think she married one of the Weaver sons or grandsons. I don't know about new management this year, I did fall requeening and had very little winter loss so I didn't buy bees this year. The patriarch, Binford, is getting up there in years and prefers to work with the bees rather than work in the office.
I know this business can be unpredictable and they sometimes have late wet springs that delay the build-up or queen mating. If they had a problem I'm sure that it was more the exception than the rule.
Last thing to note is that B Weaver has been running a no-treatment program on their queen stock for a number of years. It shows in the bees I bought from them. He incorporated SMR stock and bred for virus resistance. They've supposedly had the virus resistance tested. Anyway, I've gone from 90% winter losses 5 years ago to 8% this last year.
