Review: Worked perfectly with a 1st gen switch - We had an old Nintendo Switch that would die in like 20 minutes of playing, it got played a lot lol so battery was probably shot. Decided to give this a try and it was perfect! Easy install + fits nicely + works for about 2.5hrs with heavily intensive games
Review: Excellent option - Replaced a swollen battery on a 3yr Pixel 6, it's been only 2 days but I do see the difference from the old to new battery on use time So far is great, if a get 3 more years, then it's perfect Take your time while assembling and it will be easy

### ⭐ Avoid this battery at all costs
*by J***E on April 8, 2025*

Disappointed with Performance – Did Not Hold Charge and not working. I purchased the Luuzkla 11500mAh (2024 New Upgrade) battery for my iPhone 14 Pro Max, hoping for improved battery life and reliable performance. Unfortunately, the product did not meet expectations. Despite being marketed as a "super capacity" battery with 0 cycle count and full tool kits, it failed to hold a charge from the very beginning. Installation was straightforward thanks to the included tools, but the battery performance was extremely poor. After a full charge, the battery drained quickly even faster than my original battery. I followed all recommended steps, but the issue persisted. This is especially disappointing given the advertised 11500mAh capacity and "upgrade" claims. I've since reinstalled my old battery, which performs better than this new one. I appreciate the idea of a cost-effective replacement with an extended service life, but unfortunately, this product did not deliver. I hope the manufacturer addresses these quality control issues for future buyers.
