Deltaalphalima1 congratulations on your WHTM slew mod many said it could not be done or promised to do it for nothing and never delivered. The fact that you have produce two Modifications at different price points is great I wish you only success. I would deffinetly purchase a unit but my grip is a real one with the real switches so I just don't need it.
Now a bit of advice for the guys that have purchased it praise in public he needs to hear he is doing a good job and future customers need to know he is a trust worthy business. IF you have a problem contact him first let him solve the problem this is a very small niche market, sport it cheers
