It has a nice look to it but it uses both angular material and bootsrap with jquery. This is a lot of bloat, you have two full component libraries, this increases your bundle sizes but also can mean you could use components from bootsrap or angular, if you have multiple devs it can make following a standard difficult, one might use a bootsrap button and the other a material button. Also a lot of the components are not really properly coverted to angular components.
Looks very nice at start, then when I tried using various components I found out it takes a lot of time wasted to make things work and there's no support or documentation provided on how to set these up. NONE. Especially on sidebar, navbar, lists, tables, scrollbar. Lots of doc content is just referring to some other links, lots of demo items that attract you to buy are not mentioned in the docs at all. We bought premium support for Angular Material Pro, nothing was done by CT team to their promise, e.g. responding within 1 business day. Even when responded, information and questions asked were useless.
