Best of best… Suitable for hours of reading same as book
Amazon is not there in our country. Physical books also costly with international shipping.
But I love the reading, Previously downloaded eBooks from online websites, but I felt bad, I wanted to pay the author.
Then got to know about Kindle app, and happily purchased eBooks using Amazon and used it in my mobile.
But I feel, reading on screen is not good as reading on a paper….. Then got to know about this device
Ordered using international shipping from amazon.com
Delivered on time and device is best.
Hours of reading without feeling like a watching a screen. Best experience so far.
Feeling like, have wasted 25 years of life without this device. Stir feeling happy, I have much more years to travel with Kindle
Far better than a Kindle app, previously I used the kindle App. This device is better.
No blue lights…
If you love reading, you will love Kindle.
It will be great speed up the refund process of import fee deposit.
Also please consider adding cover for international shipping, Need a cover for kindle
Thank you

Foreign language caveat
I have owned for many years a Kindle, in which I keep now several hundred volumes. A friend gave me the new paperwhite Kindle. The latter is colorless, a drawback when looking at maps and pictures that may accompany the text. Lightweight, however, this new device offers a glare free, fount resizable clear book face that facilitates reading and makes it enjoyable. It does not tire the reader as the old bulky predecessor or holding a volume for hours. I rarely read an entire book, focusing only on the specific information in which I am interested. Novels are pretty much out of my list.
For those who read in several languages, the integrated Priberam Portuguese Dictionary (Dicionário Priberam da Língua Portuguesa, much like the version for Microsoft Word (e.i. FLIP version 10) is a reliable resource. The Priberam English-Portuguese Dictionary, though, is full of errors, often providing supposed translations totally unrelated to the targeted English word. It gives the reader only one single word, without contextual clues. Frequently, it omits available Portuguese equivalent words that one must search in other lexicons such as the trustworthy Priberam Portuguese-English Dictionary at the publisher’s website, or other reliable well-organized dictionaries (e.g. Porto Editora’s Dicionário Escolar English-Portuguese; Larousse Portuguese Dictionary; Collins English Portuguese Dictionary). Mediocre at best, the dictionary integrated with the paperwhite Kindle, obviously, may have been a low cost, poor quality alternative to the absence of such a tool. “Better than nothing”.
For readers who may utilize the dictionary in question, downloading your books to the iPad will allow the utilization of Apple’s far superior dictionary. Unlike the extremely limited version in the Kindle, the iPad tool is accurate and ample, with contextual clues.

Estoy satisfecho, cumple con lo que promete
Compré varias unidades, una para mí y otras dos para otras dos personas con varias semanas de diferencia. Todas las unidades llegaron en buen estado e incluso algunas llegaron varios días antes de lo esperado. La caja estaba bien sellada y en buen estado. A continuación describiré los pros y contras, por si le resultan útiles a alguien, pero en general puedo decir que es un buen producto.
Compré el Kindle principalmente porque no daña los ojos y en mi caso suelo leer a menudo, además ya sea por presupuesto (que los libros digitales son bastante más baratos que los físicos) o por escasez (que hay libros que es muy dificil conseguirlos en formato físico y cuando se encuentran son muy caros) el kindle me permite acceder a más libros con mayor facilidad.
Luego de un par de meses usandolo puedo decir que una de las cosas que más me ha gustado es la duración de la bateria, ya que sí es verdad que puede durar varias semanas con una sola carga. Lo único que le acaba la carga más rápido es cuando lo he usado con audiolibros, ya que se tiene que activar bluetooth y usar con audifonos inalambricos obligatoriamente. Eso sí me parece que deberían cambiarlo, ya que incluso tuve que comprar audífonos nuevos para escuchar audiolibros porque sólo tenía audifonos de cable, y que puede que al kindle le dure bastante la bateria pero si a los audifonos se le acaba entonces tampoco podrás seguir escuchando y los de cable no servirán. Sin embargo aún cuando escucho audiolibros (y tomando en cuenta que les suelo aumentar la velocidad) y a veces le activo el brillo de pantalla, igual sigue durando la bateria varios días.
Tiene brillo de pantalla que se puede controlar según la intensidad que uno necesite, tiene modo oscuro (aunque hace que a veces queden "manchas" en la pantalla por un rato cuando está activo). Algo que me sorprendió cuando me llegó fue su tamaño, pensé que la pantalla era un poco más grande (por eso incluí imagenes al lado de una regla para que se notara el tamaño), esto no es necesariamente malo, ya que al ser pequeño es muy portable, en mi caso a veces lo llevo en el bolso a mi universidad y su tamaño y peso son un gran beneficio. Sin embargo, un problema puede ser para los PDF ya que al no poder cambiar el tamaño de letra sí puede hacer falta una pantalla más grande. Se puede hacer zoom, pero es mucho más incomodo para leer
Tiene capacidad para muchos libros, actualmente tengo alrededor de 150 archivos entre libros y PDF y no he tenido problemas. Los libros que he comprado en la tienda de amazon o que he descargado gratis (la mayoría de los que tengo han sido gratuitos) tiene como ventaja que se pueden personalizar (cambiar tamaño de letra, tipo de letra, tamaño de los margenes, etc.).
En general, es un muy buen producto y estoy contento con él, lo recomiendo para personas que leen mucho o quieren versatilidad a la hora de leer. Las unicas cosas en contra que noté fue el precio, el cual para gente de mi país resulta costoso pero que en este caso al ser de decima generación y comprarlo con descuento quedó mucho más accesible, y el detalle de tener una entrada para audifonos de cable para usarlo no sólo con inalambricos, y en algunos casos la pantalla puede ser un área a favor o en contra. Además, se debe tener en cuenta que sólo incluye el cable de carga pero no el adaptador o la "cabeza" del cargador para conectarlo a corriente, por lo que al menos en mi caso opto por cargarlo conectandolo al computador.

A Perfect Finale to Off-Campus and Briar U
The Legacy was everything I hoped for and more—a perfect conclusion to Elle Kennedy’s Off-Campus world. It felt like catching up with old friends and seeing how far they’ve come since we first met them. I laughed, swooned, and even teared up at times—it’s such a satisfying send-off for a series I’ve loved so much.
One of the best parts of this book is how we get to spend time with each of the beloved couples:
Hannah & Garrett – Still as sweet and solid as ever, proving that their love is built to last.
Grace & Logan – Fun, flirty, and full of chemistry, but also showing real growth in how they handle life’s challenges together.
Allie & Dean – Emotional, heartfelt, and just as fiery as they’ve always been—Dean never fails to make me smile.
Sabrina & Tucker – Tender, mature, and grounded, yet still so full of love. Their storyline was especially touching to see.
Elle Kennedy weaves their stories together seamlessly, balancing humor, heartfelt moments, and romance. Each section gives closure while still keeping things exciting—it’s like getting four mini love stories wrapped into one beautiful package.
I highly recommend reading The Legacy after finishing both the Off-Campus and Briar U series. It brings everything full circle, and you’ll appreciate all the cameos, callbacks, and little details so much more. Plus, it’s the perfect lead-in before starting the new Campus Diaries series, since you get that emotional closure first.
Overall, The Legacy is a heartfelt, fun, and incredibly satisfying finale that left me with a huge smile. If you loved the Off-Campus or Briar U books, this one is a must-read.

The Legacy
Format: Kindle
I had so much fun with this book! Getting to see every couple again and see them navigate through their challenges in their unique, funny ways. Loved it! Tucker is still my favorite guy. Also loved how they made this like a twisted sisterhood of the traveling pant’s story. So funny.
