Great Price and Great Shipping time ... also the Items arrived in tip top shape. However, the items were not what i was expecting. I was under the impression the Volcano Silicon Sock would have been included with the Volcano kit, but it is not , be sure to add one if you buy this kit : https://spool3d.ca/e3d-silicone-sock-for-volcano-heater-block/ and i was surprised to find out there are NO steal or abrasive resistant nozzles included in this kit either, so make sure you get them - doesn't make sense not to have them included either since that is why the volcano upgrades exist. In addition, the item descriptions need some serious updating with more informed details - seems overly generalized or the admin was in a rush, needs more attention to detail. So, if anyone wants both a standard v6 short block and a volcano big block with brass tips for both block types when switching them out, then this kit is for you; but dont forget you will need the volcano silicon sock, steal nozzles for abrasive filaments like flex carbon fiber etc. and a E3D PT100 Total Upgrade Kit if your printer is still using the old cartridge style like my CR-10S. Otherwise, if you are like me, and you want the v6 assembly and the copper volcano block for high volume and high temps then i would recommend going with the following instead: 1. V6 assembly - i would recommend the titan assembly or e3d-v6 hotend full -kit 2. Copper Volcano upgrade kit : https://spool3d.ca/e3d-copper-plated-volcano-kit/ 3. steel nozzles : Ruby is the best 4. E3D PT100 Total Upgrade Kit (CR-10s needs for block) 5. E3D Type-K Thermocouple - Cartridge Style (may or may not be needed for the block) Hope this helps ... will add another comment once done installing these upgrades etc over the next few weeks as time allows, maybe add videos to - more to follow. If i had been given a silicon sock and the descriptions doen with more detail i would have given it a 5 out of 5 service - so 4 it is ... Overall, i will always buy from Spool3D first because they are doing so well in ever other aspect of this service and then some, not to mention their prices are reasonable - keep up the great work Spool3D ... get ready for me when you get the titan aqua (with water cooler) and super volcano and tool upgrade from E3D ! :D
