    Best bang for the buck

    I came upon this product through MobileReviewsEh's reviews on YouTube where they performed in-depth tests comparing the performance of different products. The FLOLAB screen protector struck an excellent balance between having both top of the line impact and scratch protection, maintaining cosmetics while also keeping my cellphone safe without costing as much as some screen protectors that improve on one to the compromise of another. Shipping from China to Canada took a reasonable amount of time, whereby it would have been nice if there were more or slightly clearer tracking updates from 4PX ("the item was recovery from the airport" makes me fear that it got stopped by customs). The packaging of the product was very nice, and the installation was quite easy, though I initially made a wrong judgment on which side of the alignment tray was supposed to be on top. My only gripes were that the cleaning wipe came out of the packet a tad too dry to really seem effective or conducive to avoiding streaking, and the instructions should have warned that you obviously have to remove the Samsung S21's factory-installed screen protector first (there is another and more cleanly installed likely PET screen protector under the basic, easy to peel scratch protection film!); fortunately, I realized this before applying the FLOLAB screen protector, but I had already wasted the cleaning wipe; at least the factory-installed screen protector already kept the once carefully removed with the tip of a hobby knife; wrongly applying the screen protector on top of difficult to see factory-installed one might be a reason for low reviews reporting the product being defective or having suboptimal results. The tempered glass feels very nice and seems quite sensitive, also transmitting light and colour to my satisfaction. It also fits within my Spigen case quite nicely. Otherwise, considering the above, I definitely recommend this product and look forward to the improvements and advancements this company will make.
