I own 15-20 of the tile sets and have been happy with them all. I use them with MapTool.

Unfortunately this set does not meet the standard set by the other e-tiles. I find that the e-tiles have a very nice look of having a grid without glaringly looking like a grid. This set does not. It does not match the other sewer tiles. There is also some sort of problem with the scale as explained on the intro page. The tiles are broken up in the middle of a grid at times.

This set is not suitable for a VTT without major graphics manipulation.

Given the price its, ok, just note it will not connect up to your other tiles very well.
