Perfectos, sin problemas.

Con un poco de habilidad es facil la sustitución del antiguo por el nuevo. Perfecto.

The ribbon cable itself looks perfect! But as to MY ability to install it successfully is a different story. I just finished the origami folding, hoping to attach the ribbon cable some time today. Wish me luck.
It worked as promised - and then some.

The repair kit came with excellent instructions and important tips - these should be followed meticulously! It also turned out that the adhesive circuit is far more forgiving of error than I expected. It took me several tries before I managed to get it placed precisely on the plastic form - i.e., I had to remove and rest it several times. The adhesive still held reasonably well, even after the fourth or fifth effort. Jose @ the calculator store is also a champ in terms of offering quick and helpful advice and support when things don't go exactly as hoped and planned.
Exactly as Advertised

Was nervous about installation but instructions were detailed and I was able to carefully follow. Parts of the process are tricky but persever. What a relief when I screwed the back on, plugged in the batteries, and HP 41CV worked again! Thank you for supplying this part.

That saved the life of my HP-41CV. You need a lot of patience and sensitivity.

Saved my HP-41CV. Easy to fit if you follow the instructions and take your time. Thank yo for stocking this item.

When my HP41CX broke down, I thought I would not be able to have it fixed at a reasonable price, given the date of production of the calculator. Then I found the Calculator Store site which provided the solution (to replace the flex PCB). I tried it and it worked perfectly for me. The process of installing is however a bit tricky and needs to take time to read carefully the instructions. They are detailed enough and have been recently updated and you can also find a tutorial on youtube.
Excellent, fits exactly and works very well (despite the application is a bit hard)

Después de 20+ años en un cajón ha vuelto a revivir mi hp41c. El conector se encontraba completamente destruido por la corrosión. El montaje de este kit es un trabajo laborioso, pero con paciencia y siguiendo el manual paso a paso lo he conseguido en un par de horas. He necesitado un x-acto de punta fina y una regla transparente para hacer los dobleces y para insertar el conector en la parte de los puertos de expansión.

Worked as expected and saved my calculator. Bending and sticking the flex pcb to the block proved being a bit fiddly task though. Glad to see my HP-41CV working again after many years.
Saved my HP 41 C

Absolutely no complaints. Prompt delivery. Good description available how to use the kit and it works just perfectly.
Great service! I am very pleased.
Works as advertised, very satisfied

Installation was straightforward from the instructions (there is also a video on how to install). Adhesive may not be strong enough for the battery contacts (nothing a few watch screws can't fix). Was able to resurrect a dead 41C.

Le devolvió la vida a mi HP41c después de 20 años!!
El gran detalle según mi experiencia es que se debe doblar adecuamente el circuito flex antes de intentar colocarlo.
También hay algunas partes que no pegan después de desprender la cinta adhesiva. Recomiendo reforzar el pegado de estas zonas con pegamento instantáneo (metacrilato). También es importante fijarse que una vez instalado en flex cable en la pieza plástica, esta calce bien con la carcasa posterior.

I was disappointed
From the picture on the website (and above) I assumed that this was a complete component to repair the HP41, not just the decal which needs to be bent etc to fit on the existing part.
Great, works perfect!

Happy, that my old HP41c is working now :-D
Thank you, Lutz
NO ha habido forma de conectarlo

Mala; segui los pasos del manual descargado, y nada; no se ha podido conectar, dinero tirado a la basura; era una pena pues tenía puestas garndes esperanzas en el producto; ya que como dicen es bastante rñeplica del original..
Si alguoien tiene una sugerencias , se lo agredeceria; muchas gracias
great solution to give a second life to my HP41C
from Anonymous on 2/9/2014
Il circuito è fedele all'originale, le istruzioni per la sostituzione sono precise e chiare, il risultato è impeccabile.
Fondamentale l'uso di un bisturi per rimuovere i pioli di plastica e una tessera plastica spessa per fare le pieghe senza danneggiare le piste. il costo della raccomandata è molto alto (18€) e i tempi di spedizione sono stati di 1 mese.

Very pleased with the product. Worked out very well following the instruction. Had my doubts about the sticky side of the PCB but it uses a very high quality adhesive so no worries! The more than 30 year old 41C went back to life without any problems after 10 years in a drawer. Took me some time to find TheCalculatorStore as a supplier of the particular part, came across it more by accident. There are likely more users that need parts so maybe an improvement of the search attributes on the website would help.
Trés bon produit

Avec un peu de patience et en suivant à la lettre les instructions (y compris celles recommandant de passer l'ensemble au four !!!) on parvient à un résultat excellent.
J'ai pu faire ressusciter ma 41CV. Merci!

Resulto muy sencillo de instalar y, tal y como se termino, la calculadora funciono de nuevo.
The product is usefull, also the documentation

works ok, quality is very good, but the shipping costs from Spain to Germany of about 18 € for 3 such small light PCBs is horrorable.
