I bought the DuraSec ones, but based on the opinion here, I think I need to get these Vikuiti ones too ..

So I have a few questions regarding the Vikuiti's ..

1) Which one to get: Vikuiti DQC-160 (just one piece for about $13.4) or Bedifol UltraClear (6 pieces for about $7.39) ..

Isn't the second option more cost economical ? I mean you get 6 pieces, so you have room if you mess up in applying the screen protector first few times. With the DQC-160, you only get one piece. So if you waste that, then you would have wasted $13.4 .. Or is there some point I'm missing here which is why people are still preferring the DQC-160 ??

2) How long does the delivery take to arrive in the US ?
