The screen is wonderful and the pre-modded shell was of higher quality.
I recently started collecting gameboy's because I prefer to play retro games on the original hardware. When doing some research, I saw the IPS screens and immediately bought it. The soldering is very easy and is highly recommended in order to use the brightness control. I also bought one for my OG GBA system. The soldering on that one is a little more difficult since it's 3 wires instead of 1, but still extremely easy to do.
Timed the brightest and lowest settings (I did the soldering) for their battery life. About 1.5h and 2.75h respectively (On a 2nd hand 600mAh battery). For me, the looks are worth it. For others, probably not. Very crisp image and I recommend it to those who want to see their GBA games in a new light.
Upgraded my 001 and the difference is phenomenal. Some may gripe about the saturation/vivid colors, but I find it refreshing. Install was simple enough, and the ability to adjust the brightness makes it worth soldering in the included wire. My only complaint is the hit on battery life. I mean, we're talking a loss of more than a half of gameplay time, and that's playing without being anywhere near the brightest setting. I've ordered the Makho battery mod kit to hopefully help alleviate this issue. If you're installing this in a HHL kit, you won't need to do any modifications to the shell. However, you'll want to use the OEM screws and membranes (my pics are before swapping the OEM membranes back in) if you go that route. You can see my review regarding that on this site as well.
Very good services. The kit is high quality, look real nice, very happy with the results. Although this is my first modification, the assembly guide on handheldlegend website helps a lot as it is very clear and easy to follow. Thank you guys !!!
