If you are looking to drastically increase your first layer quality, this is the way to go. Have in mind that you will have to boost your bed temp. to about 70ºC in order to have proper adhesion, at least with pla. Once the bed temp. lowers, you can just lift the print form the bed with no force. Other thing to mention is that the standard bed clips won't fit, since the bed will be higher, so bigger clips and z offset adjusting is necessary. If you are having problems with adhesion just give the glass a good cleaning with water and dish soap, and don't touch the print surface with your fingers to avoid leaving residues.
If you follow these steps, you will have amazing prints with outstanding first layer smoothness. I really recommend this upgrade.
