I've used Chad and Bernards software for a few weeks now.
I purposely held off on writing this simply because I was personally skeptical.
Honestly, they've surpassed my expectations.
The client is great, the plugins I've used have been incredible at progressing my GIM account.
If I have an issue, the support I receive is quick and helpful. They genuinely care about making their product great.
I've used a lot of plugins from a lot of vendors, I could say great things about a few of them, good things about some of them, bad things about most of them, but Squire might be the best product I've used.
