I will give a brief account of my experience with Specialized Crates.
I have a server with about 40 daily users, the performance of SpecializedScrates is decent I can not complain, I come from using GoldenCrates and the performance of that plugin is too bad, here I give a point in favor of SCrates.
A friend of mine gave me the plugin to test it before buying it and I liked the result and decided to buy it (I even bought it with the bug...).
I opened a ticket to report the bug which the Developer has totally ignored me on Discord even though I have passed him videos and images as well as indicating where the error can come from, 1 week with the ticket open, 0 support and it is a PAID PLUGIN. I understand that being a paid plugin does not oblige the DEV to offer 24h support, but if in 1 week has not helped me ... I can not recommend this, it is impossible, there is no excuse.
The plugin has a bug and it is that the plugin is reloaded whenever a user opens a box and the following appears in the chat:

This as I say happens whenever a user opens a box, which calls DecentHolograms and it reloads all the time, I have VoteParty and when I give keys to my users it opens like 100 chests, how can I allow a plugin to reload its dependency (DecentHolograms) and reload it like 100 times in minutes? It harms the server performance and CANNOT FORGIVE THIS, as I say I can not recommend such an atrocity, as DEVELOPER that I am also (not Minecraft plugins) I value the work and therefore I will not give 1 star, but I DO NOT RECOMMEND BUY THIS PLUGIN at least until the DEV focuses on it and offer a decent product free of bugs and decent support too.
