Good for anyone who does a lot of fractional adding.
Great product I have used the small handheld models for over 20 years and this works just as good and easier to see the numbers.

Great product for builders
this is a great calculator for builders, but I recommended having a bigger display so you could see what has been entered . Measure twice cut once

Much easier to use than the pocket version.
Grudgingly ordered this after having to switch back to an older phone and the factory wipe removed my app only to find out it could not reload the app because CI doesn't support Andriod 11 anymore and wont allow access to older versions that did. This is a must for anyone doing desk work and currently using the app or pocket version. Larger display, larger hard buttons, much easier and more efficient to use. Hopefully more durable. Before going to the app I was going through the soft button pocket version at a rate of 1 per year.

Invest & make your life easier!
I’m writing this review 5yrs later! This is by far one of the best investments I have made makes my job easier. I am a carpenter concrete foreman so this calculator helps me out a ton when I need to order material and even when I am dealing with slope percentages etc. It’s awesome and can take a beating too it’s been in my bag pouch ever since.

Coolest calculator ever for construction!!!!
Has all the features of the 4065 and the 4080 trig model. I also have the 4065 which is more portable. Not exactly portable but it's awesome!! All of the construction master calculators are incredible. Also they have a huge library of videos on YouTube and if you get stuck you can call them and there's always a person there that can help walk you through it. Great customer service. Every time I've had to call it's a real person here in the US. Can't say enough good things about this calculator and the company.

Un mio collega possiede il modello precedente di questa calcolatrice e, dopo aver provato la sua ed averne constatato l'enorme utilità, mi sono decisa ad aquistarla a mia volta. 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.

I am really glad that I bought this and relieved that I could buy it in the UK. If you work in construction it would make your life easier. It takes some getting used to the range of functions however if you are a joiner the stair function and traditional cut roof functions are great. You can input metric or imperial although the inputs are more logical when done in imperial and use the American phrases for roofing and framing. It has a good instruction booklet however the you tube channel is the best resource. The quality seems to be very good but came with a tough case too. Well worth the money.
