The Ortega Guitars RU5CE-SO Soprano Ukulele seems like a good buy, especially if you're after an easy-to-use instrument with a few extra perks. The manufacturer's description mentions it comes with the Ortega MagusPro Preamp/Pickup System, including a built-in tuner.

This feature helps keep the ukulele in tune, which is super handy for beginners and experienced players alike. It’s particularly useful if you're playing in different places where tuning can change more often.

From our research, the built-in tuner is reliable. Someone mentioned, 'Built-in tuner is nice... just have to remember to turn the tuner off when not using it so you don't kill your battery.' Another person said the electronic tuner works as expected, which highlights its overall convenience.

Just keep an eye on the battery life, since it uses two lithium metal batteries that come with the instrument. Managing the batteries well will ensure the tuner stays functional.

Besides the tuner, the ukulele features a spruce top and sapele body, which the manufacturer says gives it a warm, resonant sound. This construction is great for players who really care about sound quality.

All in all, the Ortega RU5CE-SO offers some nice features, especially the built-in tuner, which adds a lot of convenience. Combined with its quality build and sound, it seems like a pretty solid choice for its price range.
