Il prezzo è forse un po' alto, ma la facilità con cui ora riesco a gestire conversioni, somme e computi metrici per offerte è impagabile. Inoltre, guardando il libretto di istruzioni, sto scoprendo tutta una serie di funzioni che costituiscono certamente un valore aggiunto. La confezione, al posto del guscio di plastica standard, includeva un bonus, ovvero la custodia protettiva "armadillo gear". Questo accessorio temo che in realtà abbia notevolmente influito sul prezzo di vendita - la stessa calcolatrice, infatti, se acquistata in un negozio fisico negli US ha un costo di gran lunga inferiore. Ma io non volevo aspettare di andare ad acquistarla direttamente e comunque l'idea di una cover protettiva mi sembrava un'ottima cosa per proteggere la calcolatriche da danni da caduta quando sono fuori ufficio. E questa copertura in gomma effettivamente protegge la calcolatrice da qualunque tipo di urto, peccato però che ne aumenti l'ingombro in maniera quasi eccessiva, rendendo impossibile di fatto il trasporto in tasca. Inoltre, la custodia è larga e raccoglie quindi ogni tipo di residuo e polvere; il gancio dello sportello, infine, rende difficile poterlo aprire e si deve sempre operare con due mani. Quindi, questo mi impedisce di utilizzarla per lo scopo per cui è stata acquistata - ovvero una gestione facilitata anche durante le fasi di lavorazione. Dato il costo, ho ovviamente cercato di acquistare la cover standard separatamente (ora devo rimuovere lo scudo protettivo quando sono in posti senza piani di appoggio confortevoli) per avere una protezione seppur minima proprio nelle occasioni che contano, ma senza fortuna. Non posso quindi dirmi completamente soddisfatta. L'oggetto in sé è ottimo con perfette funzionalità ed un funzionamente intuitivo, ma l'imposisiblità di fruirne come pianificato ne diminuisce l'utilità. ## Frequently Bought Together - Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator for Contractors, Estimators, Builders, Framers, Remodelers, Renovators and Carpenters - Aproca Hard Storage Travel Case, for Calculated Industries 4065 4080 Construction Master Pro Calculator (Case Only) - Calculated Industries 2140 Construction Master Pro Workbook and Study Guide | 4 Comprehensive Sections | Site Development | Footings, Slabs, Walls | Framing | Finishing |Practice Problems, Answers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/267822250-4065-construction-master-pro-advanced-construction-math-feet-inch-fraction](https://www.desertcart.ae/products/267822250-4065-construction-master-pro-advanced-construction-math-feet-inch-fraction) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-07-27*
