My first purchase with Technology Outlet was satisfactory. The package - a BLtouch - arrived on time and well packaged. They did send the wrong version however; a BLtouch with the accessories for an Ender3, whilst I needed the BLtouch only. I am not convinced however that Technology Outlet is the most price competitive retailer. This may be offset with a good level of customer support, but I have not had need of this yet. I will try some of their filaments to see if they are better than other cheaper options out there. The BLtouch that I purchased is fantastic and dramatically improved print adhesion.
