Review: Excellent product for the cost! - I can't believe the value for this product. Now - I installed my new battery yesterday using the tools, and it's only been ONE DAY, so you might take this with a grain of salt: The tools: Worth the cost on their own. Make the installation SO much easier than getting these tools separately. The screw drivers pivot relative to the base, so work GREAT via one-handed operation. The battery: I EXPECTED a worse-than-OEM battery. In one day of use, I am seeing a HUGE improvement. Qualatatively - it went from: 6-year-old battery feel - meaning my phone would go from 100% to 95% within minutes, and then generally just shut off within 30 minutes to a ~1-2 year old battery feel - meaning the battery lasts the whole day (only drained 25% in 6 hours) Overall, I recommend this product. If you think the battery should be better, you should not expect it to be this affordable! Excellent deal for the price overall.
