Customer ratings for Repair kit for HP-41c battery bay and expansion ports

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.

Resulto muy sencillo de instalar y, tal y como se termino, la calculadora funciono de nuevo.

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!

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.

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.

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

Happy, that my old HP41c is working now :-D
Thank you, Lutz

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.

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.

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.
