Have you guys experienced this? I keep losing connection. It's actually MUCH worse than if I just used my tablet to control the spark.

Yes. it has several discussion threads about it here. Mine did it again to me today. Problem seems heat related.

Such a shame. I've been reading them. I am very close from returning it at this point.
