Thing is, reviews from clients don’t really apply here. You can be a very bad lawyer with very happy clients. You can also be a great lawyer on a bad case and wind up having a pissed off client who finds it more convenient to blame the lawyer than accept reality. Only a peer expert would be able to determine that you’re incompetent. For the software devs here, ask yourself how a non-technical person could find a great software developer to hire, it’s an analogous problem.
